It seems there was a corrupt file that wouldnt let my keyboard work when windows started. So I loaded my starter CD's and let it use repair. After it was done an hour later, it let me log in and everything was fine...till I found out it made another problem. It seems when I loaded the CD's it overwrited my old Windows, and made a whole new one or something, yet my old stuff is still there. But it wont let me use some Microsoft specific programs. And then it started saying I had to register my Windows. I'm currently not at my house so haven't had time to use my Authentication Key from that Windows. But if I already used that Key the first time, and its asking again, Im thinking it wont work and will want me to buy a whole new Windows. Is there anything I can do to fix this? PS Kimsland, I posted this again in this forum because it seems more suited and more likely to get help for this problem.
