Flash CS4 randomly won't open .fla file

Question

All I get is an error box saying: "Unexpected file format."

Everything was going fine until I did some simple action (removing a few frames I believe), then Flash crashed and I haven't been able to reopen the file since. It opens other .flas just fine. I rebooted, but to no avail.

Any ideas? This is an important project and very frustrating. Thanks.

Answer 1

The only time I have ever seen the dreaded "Unexpected file format" crapola is when I try to open an FLA saved in a newer version of Flash. If you don't have cs-5 installed, and no one else touched the file then you may be SOL. Perhaps you can recover a lot of what you need with a decompiler.
