I too am having this problem - I think it is a Vista ownership problem since I don't have access whatsoever to the programdata file catalogue as any user. FP won't minimise or close and only way out is a Task manager "kill".
I reinstalled using a specified file on a different drive - I have my system one one drive and have a working disc completely separate (maybe not necessary, but I have been doing things this way for a long time!). The reinstall worked fine until I restarted the system when it seemed to revert to the previous version and reported the error again. Working fine atm since I have just reinstalled & not yet rebooted!
Hope v2010.101 fixes this!

You're still on 100? 102 is out.
