Hi. I'm trying to rip purchased CDs into WMP11 in Vista. I get the following\nerror message..."Windows Media Player cannot play, burn, rip, or sync the\nfile because a required audio codec is not installed on your computer."\nHowever I can play installed music. It's ripping it wont do. This is a recent\nphenominon. I have downloaded various codec packs without solving the problem.\nIs there anyway to 'repair' or re-install WMP11?\nHelp please.
