    Hi everyone,

    I think I lost my whole work of yesterday. But before redoing all of it,
    i have to ask:
    why? and how?
    From 2PM esterday, all none of my .cpr files will open.

    I get this message:

    The project "xxx" is not valid.

    Same message with every file, and every .bak

    Is there a way to recover these files?
    Could I extrac tracks from it (I have cubase 5, also, if I have to use it).

    ANy help is welcome.

    Small hint: on a slower computer, I can see that the "not valid " .cpr
    begins to load but becomes unreadable after 15%.

    On an italian forum, I understood that Guitar rig could cause this. And
    this could be my problem.

    Is there a way to remove a part of the CPR so that the rest would load?

    Or would I use a newer version of cubase to extract tracks from the cpr?

    Sorry to hear that. There is not a lot you can do with an invalid
    project, short of reverse engineering the entire file format.
    Do the files have a reasonable length? Most "invalid projects" I've had
    were 0 bytes.
    What if you create a new project, save it, and reopen it? Is it invalid
    right away?
    Just to see if there is something wrong with the configuration, could
    you send me one? See if I can open it. My email address is my name at
    the domain below.

    They have the right size.
    It really seems that one of the plug ins that i used is the culprit.
    Not at all.
    Thanks for caring.
    I'll send you a file right now.
    (I assumed I had to write you name like this: josgeluk).
    We'll see if the mail comes thru

    I have been thinking about this a bit, but I'm confused. Apparently the
    issue arises when a project in memory gets to be bigger than 1.3Gb,
    which is not an awful lot. AFAICT the project file however (.cpr) never
    grows any bigger than a handful of Mb. I've had many projects with more
    than 1.3Gb memory usage, and that can cause problems, but I don't
    believe "Invalid project" is one of them. Any other opinions?

  9. Hallo,

    It doesn't seem to be the great help but some people in different
    web-forums (is this the right word? i don't know 'cause my native
    language is german) say:
    - that Steinberg know this problem and is working on it
    - contact Steinberg and you can send them the corrupt *.cpr and the
    number of your USB-Dongle and they are able to repair the file.

    Hope that's a little gleam of light?!

  10. I don't remember coming accross anything like this...if the project
    contains loads of midi stuff then I've no idea what I'd do...but if it
    is mainly audio, I'd drag all the files into a new project. I've done
    this with ease when I've wanted to work on a Cubase 5 song using
    Essentials4 which I have on a small laptop which I use when I go on
    hols etc.. Its a bit of hassle but it could be easier than starting
    over...Just a thought.....LL

    Thanks for you input. Would you have a reference I could read?

    For this time, I won't be able to wait and see if Steinberg can fix my cpr.
    I'm already half way of recreating my song.

    This time, I carefully unload and reload the song every hour to see if
    the many many many safety savings I made are not actually crap.


    PS: your english is very ok :) (at least for a french guy)

  13. Hallo, (
    Well, i've only found an older discussion here:
    (attention: it's a discussion in german but i hope, you have somebody to
    translate it or you know enough german words?).
    The discussions i read about this lead nearly always to the same - the
    recreation of the song.
    Making Backups (i know, who makes backup when being concentrated) should
    help.... and saving projects under new names.
    Thank you. Let's see, what the native english say.... :))

    Basically, one guy says: send it to Steinberg support with the dongle
    number, and the other guy does that, and he gets a reply within hours
    asking him to mail the project file. So he's happy. Sounds convincing
    enough to me. Consider giving it a try, if it is still an option.

    Of course, it was mainly midi and plug in stettings :-/

    For the audio parts, I'm just starting to load the audio files, but it
    won't be a problem.

    2 things: this "memory" problem seems to happen from SX2. My problem is
    with SX1. So I donot know if it applies.
    The second thing is that 5 hours later after I discovered the damages,
    I recreated my playback wuite nicely.

    regarding Gerd-Ulrich's remark about regular safety savings:
    I actually do this . And I recently activated auto-back-up function,
    thinking that it could help in such a situation.

    But what do you think happened? Well, after 15 different manual savings
    with different names and 20 auto bup, I had only 35 useless .cpr on my
    hard drive.

    Only the first cpr of yesterday is abled to load, but all the tracks are
    missing. I can only see the VST-i channels.

    What happened is that what was in memory was ok, but cabase was saving
    crap each time. I would have noticed if I had unloaded and reloaded the

    I cant' help but think that it could have something to do with the fact
    that I have 4Go of physical memory with a 32bit O (WinXP).
    Really, I can't wait to be able to try out a 64bit OS. Following the
    advice I got here earlier, I'll be waiting for WIndows 7 to try it out.

    Going to try and reboot this thread. I use cubase 5 and one day when I went on to cubase all my projects had disappeared. After doing a deep scan of my harddrive i managed to retrieve one of my project files and the .bak files for it but when I try and open it it just says "Invalid File" and i can't open any of the .bak files on a new project. The files are all midi. Any suggestions to try and get my project working again?
