When I try to double click on any media file (ie. mp3, wma) in Windows Vista Home Premium, Windows Media Player 11 doesn't start to play the file although these file types are associated with WMP.
When I try to right click on the media file and choose the 'open with' option, then choose Windows Media Player, an error message appears says:
The parameter is incorrect
I have to start WMP manually, then play the files with it! So what's the problem?
