I'm not sure, but here's an idea. You might want to try this after completing a work unit, so if anything goes wrong, you don't lose the data and points from that WU.
Boot into Win7 and install F@H using the same details (ID number, team number, etc) as you entered in XP. Then copy (not move) the 'work' folder from the XP F@H folder into the Win7 F@H folder. When you run F@H now, it should continue from where you left off in XP.
If this doesn't work, there must be other files that need to be copied over, like FAHlog.txt, or some incompatibility problem.
Another idea, and probably easier. You could try copying the whole F@H folder, including the work folder, from XP to Win7. Of course, if you're regularly swapping between operating systems, you'll have to copy the folder each time before running F@H.
No guarantees this will work, as there might be other files or registry entries I don't know about. Hang on for some better replies.
