I am operating on Windows vista. Iused to be abble to play my library of music and watch videos and everything but the last couple of days everytime I try to play any kind of media on it wont play at all. It somes up with " Windows Media Player encountered a problem while playing the file. For additional assistance, click Web Help" When I click Web help I go through all the steps I should but the all that they suggest is fine on my computer. Except that it gives me the option of contacting my computer manufacturer and mine doesn't even come up. I have an ASUS. I have no idea what to do. can you help. I would rather not just not use WMP like you suggested someone else.
