Can't open cartoons suddenly

I’ve been working on a cartoon and now I can’t open it or any other. The message “unexpected data found” comes up when I try to open it from the toon boon library. Any ideas?
Thanks,

no backups, sheesh!

omg! I hate that! :-<br />
Sorry bud… I feel for you.

Don’t let it get you discouraged. I have had this happen to me a couple of times.

The good news it that it almost always comes out better the second time round!
