If you do any work with Adobe Captivate, you probably have experience with Captivate's tendency to corrupt files. The last Captivate project I worked on gave me a chance to get reaquainted with this feature, so I am posting the solution which saved my work:
First, you must know the exact size of the old project. If you are using an odd size, be sure to note it down. Create a new, blank project at that size. Select "File>Import Slides/Objects" and import all the slides and their objects from the corrupted project. If you don't see any slides to import, you are probably out of luck.

Can I just say thank you very much for this article. You've just saved me alot of work!
Thanks a ton dude! Saved me a 243 slide project and about 20 hours of effort from going waste!
Thank you so much, you have just helped me to rescue over 100 hours of work I thought lost for ever. God Bless you!

Thank you so much for the post. You saved my life. Saved me from having to re-do the project.
I already tried that! Don't you think I would have tried that? (Remember that scene from War Games?) Yeah, but thanks anyway, this didn't work for me. I hit import and Captivate crashes. Guess I get to start over. I love Captivate!
I tried this as well. NO LUCK! I get to start over as well.
Note that this will no longer work at all on captivate 5, as far as I can tell.
