When I try to open the User Account folder under the Control Panel, my system freezes and I cannot edit my account info and preferences. I recall that I received an error when I was installing Windows XP Pro saying that a file was not found and I'm thinking this has something to do with that error. Has anyone ever had this problem? If so, what did you do? Does anyone have any suggestions? Should I just reinstall or is there something I could do. Please help. Thanks.
