Thanks but it says "STEP 2. Reboot your PC and go into Safe Mode when your PC is rebooting, by tapping F8 during the black screen with ~4 or 5 lines of text which comes before the Windows loading screen, and then selecting 'Safe Mode' as the startup type, and 'Windows XP' as the Operating System." It says to use Windows XP. I use Windows 7? What do I do now?
