Ok straight off. I have been on computers for 10 years or more. I have NEVER seen anything like this. I have no screenshot but... When i was trying to play a file in kazaa (which of course uses the WMP) the file "played" no sound, and it would skip 20 seconds at a time. No file could be played. I am baffled. My computer is updated regularly. Funny, this only appeared after installing "Critical Updates" of the MS site. PLEASE HELP! Many thanks in advance.
