Windows Media Player 11 Problem

-= I just had a complete reinstall of windows xp on my pc… but… by the time I opened windows media player 11 and played a song… WMP simply display “opening media” for almost 5 minutes, then after that… everything plays normally… but if I shutdown the computer while there is an opening-media-delay-syndrome… there is an error message saying something about windows media event sink window… I tried to roll back to WMP9 but still… the lag persists… any ideas how to fix this…?

-= Also, I forgot, Windows Live services are also delayed… But RealPlayer & other 3rd party media players are not lagged…

-= These are my curretly installed media players: RealPlayer, Media Monkey & WMP11…
