I boguht two different CDs of VC before and i'm facing the same error. I had this problem in past and i fixed it to but i don't remember it anymore. Let me clear one thing more i've just noticed:-
Last time, i had the same problem with VC:MP. Besides with this problem, themes of some applications changes to classic view. I'll install Serivce Pack 3 and will check if i get the same error.
