“Windows Media Player Server Execution Error”-Windows 7

I am experiencing trouble with Windows media player. Each time I try to play any media be it video,mp3,mp4 etc, I always get this irritating error "C:UserPublicVideosFilename.wmv Server execution failed". I have always played these same files with vlc media player and therefore the problem lies with my Windows media player. Could someone help me fix this?
I am running windows 7 ultimate 32-bit.Thanks in advance
