anyone have this happen? I played all day yesterday and had trouble shutting down last night. When I logged in today, I received a windows error that says the program no longer exists. I tried to run it again, but it told me there is no program associated with this shortcut and prompted me to delete it. The same thing happened when I tried to run it from the program menu. So I go to look, and poof, its simply not there?? is this a known issue? should I try to repeat it if its not??
