60 Day Free Trial

I have just activated my 60 day free trial, but when I try and update drivers or clear clutter it keeps telling me I have to purchase it. Are these seperate paid programs? If so it doesnt seem worth purchasing the full thing if Ive got to pay more money out I may as well not bother plus. If not how do I get the damn thongs to work properly please
