Repaired lately? Any new windows updates, driver updates... I had a ton of that hit me all at once, right when some patch came down too, and it was a mess till I figured out what went to what, if you know what I mean? My optimizer suite got a major workout, too.
Oh... one beginner question I shouldn't have had to EDIT to ask... what version do you have? 1.0.6.? That's the newest.
