The morning of January 2nd I woke up to a lovely message from my computer. When logging in I was stopped and told I had to activate XP. Thing is, the OS is activated. Once I click "yes" on the screen that asks me whether I want to activate or log off, the activation box pops up, and then tells me XP is already activated. From there my only option is clicking exit, which logs me off. This broken cycle is driving me mad. I still have safe mode and command prompt access of course, just no knowledge of how to fix it. Help plz?
