Project Incompatible with Program after Scrivener Crash

Last night, when I tried to close the program, Scrivener crashed. I’d saved my work for the night but upon trying to reopen it this morning to continue working on it, found that the file was now “incompatible with this version of Scrivener.” I’m able to open another version of the program, but that’s about 1,200 words short of what I had.

Not too many words, but enough to make me upset. Is there any way to open the original file and get those words back?

I found part of what I’d lost in the RTF files, but is there a reason why Scrivener crashes whenever I close it? Is there a way to fix the crashing?

I’m running Windows 7.

Might want to post everything you know related to the crash and what happened in that thread.
