When I try to play my MP3 music in WM9 (Windows Media Player 9) I get the following error code C00D11CD. I have downloaded the update patch #814129 which is supposed to correct this problem and I still have the problem. Any suggestions ?????? Out of 11 mp3's only one will play in the WM9 player.. My OS is XP Professional Version and I have redownloaded the WM9 as well and still have the problem.
