I just came back from a lan party. On the first boot, it didn't detect my dvd drive, and then, when I rebooted, all was fine except for one thing: Windows XP asked me to reactivate it because too many hardware changes were made on that product key. I enter my key and it says it's invalid because of the hardware changes.
I then go on the official XP support page and try to e-mail Microsoft. Apparently, each key has 2 free tries of each kind of support(Telephone, E-mail, Chat) but it refuses to let me have one(because my key is invalid) and tries charging me $45 to get support!
The only possible hardware change is when it didn't detect the dvd drive that one single time. This is a new computer and I have never changed a thing on it. I don't know what to do, I'm given 3 days to reactivate it and then I wont be able to use the computer anymore.
