I'm intrigued about why so many people are experiencing "corrupt" files all of a sudden. If that truly is the issue then there are a number of concerns that I have, given that this doesn't seem to have been a major issue prior to the "upgrade":
1. Is it Express that's corrupting the files?
2. Is the latest version less tolerant of file issues that have always been there?
3. Why don't I get a dialog box like one of the other users telling me how to fix it?
