I'd say Service Pack 2 is your problem! Many people have complained about it ruining games! Someone else may be able to confirm this as I havent installed it yet as I have read about many problems with it. Somewhere there is a list of all the programs that dont work once Service Pack 2 is installed, but I cant remember where it is! Search the forums as I think there is a link to the site that details the problems. But I do feel you will be reformatting again very soon!
