    Flash CS4 Unexpected file format

    hwormser Level 1

      I'm suddenly getting an "Unexpected file format" error on virtually every Flash CS4 file that I try to open. These are files that I created and I'm trying to open tham on the same computer on which they were created. The only thing that I can think of that has changed is that I installed some new fonts, so I deleted those, but that hasn't helped.


      I've tried retrieving files that I had backed up to a server, and those give me the same error. The only files that I AM able to open are 1) a test file that I created in CS4, saved, closed and reopened, and 2) files that had been created in CS3.


      I have hundreds of files that I need to work on, so any suggestions would be most appreciated.

          hi there hwormser


          It seems that this was caused by the .fla file you were trying to open being made in a newer version of flash, possibly adobe flash CS5. you might try to open it with adobe flash CS5 then click File>Save As>Save as type>Flash CS4 Document.


          hope this helps!
