hi, I have windows vista ultimate 64bit and used the timestop crack to crack it when I first installed it. Now I needed to dual boot w/ XP and apparently one of the cracks (I had a problem w/ the crack so I installed a couple of them) and one of them caused a problem w/ the vista crack and now it shows on the right bottom corner "this copy of windows is not genuine" and the desktop background sometimes disappears. it's important to note that the aero interface is still working and the activation message appeared once and asked me to activate. which crack should I use? can I use the timestop even though my problem now is the windows genuine check and the activation and not only the activation?
