I've never had a problem with Windows Media Player before and I use it on a daily basis. Today it's decided not to load - it doesn't give any error messages but it just does not work. It's not the shortcut that's the problem because I've tried it from C:\Program Files\Windows Media Player\wmplayer.exe. Nothing happens. The only thing that has changed today is that I've loaded WinDVD Platinum v5. Can this have caused the problem?
