CS4 - Cannot open my project

Hi,
I was working on a project and when I tried to export in Media Encorder I had this error:
- Source File: C:\Users\toto\AppData\Local\Temp\Sans titre_33.prproj

Could not read from the source. Please check if it has moved or been  deleted.
So I restarted my computer and now I cannot open my poject in Premiere Pro CS4. I can create a new one, but my project refuse to open. I only get the progression barre and it freezed just before the end of the loading...
Help me please ?!?!?
Thanks and sorry for my english

I tried to import my project to a new one:
it started to load and it freezed just near the end (I killed the process after 6 hours)...
I tried te rename my media folder and it is the same... Premiere is not asking me about the path of my files.
the only thing I can get is to reload a 5 days backup project... So I've lost around 30h of work...

  • Cannot open Book Project in iPhoto

    I'm working on a Mac OSX 10.9.5 and iPhoto 9.5.1 (902.17).  Last January of this year I started a Book and have worked on it at winter and spring--it is about 90 pages long with text and photos.  Yesterday I went to open the project and all I got was a spinning wheel -- it will not open up. I went  in to Utilities and repaired the permissions and I repaired the photo library by clicking Alt and Command--still cannot open the project.  Would anyone have a solution?

    Hi Old Toad: Thanks for the prompt reply.  I could NOT locate the iPhoto preference file, com.apple.iPhoto.plist.
    I downloaded Find any File and got this:

  • I cannot open my project.

    I cannot open my project. The dialogue box tells me that my G Drive (External) is missing, yet I can see its icon on my desktop.  Nothing in the G Drive will open.  It was fine when I was last editing this project.

    Hi
    Nothing in the G Drive will open.
    Not without starting FinalCut - just in the Finder - either ?
    If it doesn't open in the finder - it's broken and neither You or FinalCut can reach it - it needs to be repaired.
    First to be tried is to start Disk Util tool
    • Does it show up here ? - if so -
    • Run Repair Permissions (most probably grayed out - then test next step)
    • If still problematic when tried to be opened
    • Run Repair Hard Disk

  • Encore CS3 cannot open CS2 project: folder cannot be found

    I created a project in Encore CS2 under Win XP, and when I try to open it in CS3 under Vista, I get an error of
    Cannot open project; The folder for this project cannot be found.
    Disregarding the fact that I haven't changed, moved or deleted any subfolders or files and the drive has the same letter and label as before, why the heck doesn't Encore at least give me the opportunity to direct it to the correct folder? I can do this easily in almost all other applications, like InDesign or Dreamweaver. Shouldn't this error have come up in the first few days of beta testing? (Uh, it
    was beta tested.....right?)
    I tried looking in the ProjectPrefs and ProjectWorkspace xml files, but they don't have any folder info. Searches in the knowledge base, forums and newsgroups have turned up nothing. It seems my only choice here is to recreate the fracking project from scratch!

    >(Uh, it was beta tested.....right?)
    No. It wasn't. The Encore team is so good at coding and spell-checking that the Product Manager and the Director of the Production Studio project both felt that beta testing was not necessary this time around.
    It's really pretty impressive that so few bugs have turned up in real-world use considering that both internal and external beta testing was shelved for this release. The additional resources that would have been used to test the app were sent to the Photoshop team to ensure that the CS3 release of PS was flawless.

  • In CS4, "Cannot open file" "Please upgrade your plug-ins..."

    Greetings,
    I am using InDesign CS4 on a PC. I am trying to open an .indd file created by our marketing department. I don't know what version of InDesign they use nor whether they work on Macs or PCs.
    When I double-click to open the file, I get a "Cannot Open File" popup box. The box reads "Cannot open docname.indd. Please upgrade your plug-ins to their latest versions, or upgrade to the latest version of Adobe InDesign." It then lists 18 different plugins:
    ASSIGNMENTS.RPLN
    TEXT.RPLN
    SPREAD.RPLN
    MASTER PAGE.RPLN
    TEXT ATTRIBUTES.RPLN
    .... and 13 more.
    When I go to Help > Configure Plug-Ins, I can see that I do have all of these plug-ins. But apparently they are not the latest versions.
    Anyone know how I can update these plugins? I have searched for them on the Adobe website, but no joy.
    Thanks in advance.
    Jen

    It's a safe bet that they are working in CS5. The only way to get those plugins is to install CS5 on your machine.
    You could ask your marketing department to export an IDML file from CS5, which you can open up in CS4, but it might fail horribly (and it's guaranteed to lay out incorrectly if they've used any tools in CS5 that aren't in CS4). If you rely on this workflow, by regularly using a document going back and forth between CS5 and CS4, chances are very, very good that it will fail at a critical moment. The only really safe thing to do here is to get everyone using the same version of InDesign.

  • Cannot Open New Projects Created in Premiere 8

    My software is Premiere Elements 8
    My system is a Dell Studio 17, i7-720QM, 6MB Cache, 8GB DDR3 SDRAM.
    I ran into a third problem using PE8:
    1.  After I open a New Project in the PE8 Welcome Screen, sometimes the work area refuses to pop up on my screen; no Monitor, no Timeline, no Task pane.  When I relaunch PE8 and try to open the New Project I just created I get a message "...cannot open projects created with Premiere Pro"
    Has anyone experienced this?  Do I simply reload the software?  I recently downloaded the PE8.0.1 patch.
    Thanks for any assistance.

    I too had the same issue - along with an inability to (re)open video projects.  I did a few things.
    As long as I created the project using the DV - "Standard 48kHz" setting, it worked.  Selecting "Widescreen 48kHz" allowed me to save the project but I was unable to open it, receiving the error you are getting about needing to use Pro.
    The second issue is an inability to open an existing project.  Premiere launches, a progress bar shows "loading....1%...100%" - then nothing happens.  The workspace is empty and all menu options are disabled.
    First - install 8.01, and reboot!   The installer doesn't indicate that you need to.  I continued to have the same problems until I rebooted.
    Second - upgraded the ATI drivers from the Dell website.  Apparently my 2-week old Dell XPS-16/i7 laptop came with drivers from 2009 - go figure.
    To recap, 8.01 (+reboot) fixed the "need Pro to open" issue
    Updating ATI driver from Dell website fixed the "can't open existing project" issue.
    And while on the Dell website you'll notice lots of drivers that need updating.  I did them all.

  • Cannot open score project settings...

    Hi all!
    I have this wierd issue on my laptop. I've stripped some songfiles made on a MacPro, down so they only contain the score. No audio instruments, just some of the plugs are still there. When I open the files the page setup looks different. Even though I've set it to print on the same printer, the margins are different and Header info is off the paper. So I try to open score project settings and find I cannot. I wandered if it might be a problem that the project was made on two screens and that the prefs window is actually opening off-screen. I've never experienced that before but who knows. So I try Exposé to reveal all open windows but Exposé fades out floating windows so if the prefs are out there, I can't see them.
    has anybody encountered this problem and found a solution?
    Sincerely, Ginge

    one more thing: the off-screen dialog box hypothesis is wrong. When flipping through the different menues in the "project settings" window, they all open except score project prefs. I can open it on a new file created on this laptop though.

  • Cannot open saved project

    Hi,
    I created a project in the project builder and I defined several WBS elements. I also specified a start and finish date. I saved the project and the project details tab closed. Now, I can see the project in the Worklist tab under the Last Projects Processed but I cannot open it (double click or right-click Open). I get no message, just nothing happens. If I try to create a new project with a similar id, I receive "Project I/nnnn is currently being processed by MYUSER".
    What do I need to do to be able to access the newly created project and be able to change it?
    I'm using SAP R/3 Enterprise IDES
    Thank you,
    Petru

    please don’t use work list, as some time due to config setting that can happen.
    Use Tcod - CJ20N---> Project-> Open--> enter your Project ID.

  • CS4 cannot open CS4 file - upgrade plugins

    I HAVE searched the forum, but cannot find a real answer to this...
    I've been given an .indd file. It was created in CS4. I am attempting to open it with CS4.
    I get that message "Cannot open "name.indd". Please upgrade your plug-ins to their latest versions, or upgrade to the latest version of Adobe InDesign"
    I have the latest upgrade of CS4, as does the author of the document. I see the plugins in the Plug-Ins folder.
    What do I need to do to be able to open this file? (Actually there are about 20 of these "unopenable" documents)
    Thanks!
    (I am new to InDesign. My company uses Quark.)

  • InCopy CS4 and InDesign CS4 cannot open file at the same time!

    I have 2 editors that make changes in my indd file. The one editor is able to open the file concurrently with myself (i'm in indesign) just fine. But when the other editor wants to open the file....I cannot open the indd file and vice versa. We are PC based.
    shane

    Yes, we are all working on the same server.
    And Yes on the Editor A / scenario 1  (Designer opens file and Editor A opens file concurrently). works fine.
    Editor A closes out of Incopy and so does Designer. Editor B opens the file and Designer tries to open the indd file and now the designer gets the warning: Cannot open document. You may not have permission or the document may be open already. This is the same error if the Designer opens the file first and Editor B tries to open it while the designer has it open.
    Editor A and B are able to have the file open at the same time no problem.
    Also this happens to all indd files that Editor B tries to open. So it is not linked to a problem with the file.
    one other note: on the server just above the indd file...when Editor B has the indd open in InCopy... a 'temporary' Indesign Lock File appears.

  • Cannot open any projects Premiere Pro CC

    Hi,
    I am trying to open a project that I created for a corporate client as they need it in a different format.
    To my horror it would not open. I tried opening all my other projects and I keep getting the message "This project contained a sequence that could not be opened. No sequence preview preset file or codec could be associated with this sequence type".
    The client is a news website and they are under tight deadlines.
    This happened after I was asked to sign in again to my creative cloud account as creative cloud was telling me that I had not purchased any software.
    It is such a disappointment.
    Regards,
    Joe.

    Thanks for the follow up.
    Just to confirm...
    at this time, Project Assets will not open with any new projects. But, if you take an old project (which has been saved closed before the problem set in) can you open that project and use an opened Project Assets Palette?
    If you have not already, please work through the suggestions in the link posted in post 1 of this thread. Do any of them work for you?
    In the meanwhile, let us delete the Adobe Premiere Elements Prefs file and, if necessary, the whole 12.0 Folder in which it exists.
    Local Disk C
    Users
    Owner
    AppData
    Roaming
    Adobe
    Premiere Elements
    12.0
    and in the 12.0 Folder is the Adobe Premiere Elements Prefs file that you delete. And, if the does not work, delete the whole 12.0 Folder in which the Adobe Premiere Elements Prefs file exists. Be sure to be working with Folder Option Show Hidden Files, Folders, and Drives enabled so that you can see the path cited.
    Also, be sure to be working from the 12.1 Update of the program. The 12.1 Update is accessed from an opened project's Help Menu/Update.
    Thank you.
