Does it help?
Also have a look at THIS thread
thanks for responding i’ve read the tread you linked but i can’t format my pc at this time:| and i think that reinstalling windows over the copy i’m running won’t be a gret idea 
i’m trying other solution but still nothing.
tnx for help anyway
if you have any idea …
Update Windows Media Player to version 10 and see if it works
Btw, do you use any other player?
Maybe some file assotiations could be due to this…
