Hi I'm sort of a newbie at this. A couple days ago a pop-up appeared telling me my windows 7 wasn't genuine so how do i fix this. I'm not sure if i should use a loader or something. I have windows 7 7600 rtm x64. I've tried Daz's loader but it always ends up getting stuck when i open it and always says "please wait". I also looked through some other posts regarding this but I'm still sorta confused.
