So I have been using my windows vista fine now for a while...it was activated and everything.....then when I logged on to my computer today, a pop-up came up saying to activate windows now or later....then when i got to my desktop, another pop-up came up saying this copy of windows may not be genuine, windows dreamscene isn't working, or something like that... What im wondering is if anyone knows a way of getting Vista Genuine again...I tried using VistaLoader v18.104.22.168, and it said it worked, but when i rebooted, the "this copy of windows is not genuine" was still there...I have Vista Ultimate SP1 and i really need to get rid of this and get my vista activated again. Any help appreciated. EDIT: I also tried using the vista ultimate keys in this link: http://forums.mydigitallife.net/threads/2581 but everytime i try this comes up "Windows Activation Error" "A problem occurred when Windows tried to activate. Error code 0xC004E003. For a possible solution click More Information."
