I've been working on a site for 3 weeks. I just finished putting in 2 more hours tonight when the program crashed (and then reopened a large error window). When I reopened the program, it offered to recover an autosave. When the autosave opened, it was the initial version that I had created 3 weeks ago. Fortunately I made an export 2 days ago - otherwise, all the work I have done is lost. I'm trying to use Win7 backup/restore to recover a file from a few days ago.
This is very disheartening.
Windows 7, plenty of horsepower, disk space, etc...
