I have a problem. I had to format my pc and I put windows xp on. That was about 2 months ago. Now all of a sudden when I put my pc on it says that I have to activate my windows. Then I press ok to activate. I then have to log into my user account and then its says loading personal information. It does that for about 5 min and then a window comes up that says my windows is already activated. I then press ok again and then it does absolutely nothing. It doesn't go into my account or anything. When I restart it does exactly the same again. Please help!!!!!
