@Ernie  Are you including the .cache file when you do so? That's new this year. So for example, if you have a file named john_smith.20i, there will be a corresponding john_smith.20i.cache file.  You have to copy both, from what I've been told, if you are manually moving them around and using database repair.  

Alternatively, if you have just the john_smith.20i file, you can open it and then save and the file will be added to homebase with a new .cache file. Of course, that'd be painful if you have more than 1.

Feedback is welcome.. we're really trying to understand if these changes are just not sufficiently communicated, or if the expectations aren't matching the reality.
