|I agree with OtheHill.|
But, here's a quote from another site regarding resetting WMP if you'd like to give it another go by deleting these two registry keys:
"it's an extremely last resort measure, but if you feel
it's necessary, the two registry key paths are:
Making sure that WMP is not running, nor are any applications or applets
that can use Media Player (some chat clients, some messaging clients, etc).
Deleting the nodes will force Media Player to think "hey, I've just been
installed because I have no registry keys". This doesn't re-register any of
the DLLs though."
