Hi Chris,
Try reinstalling the Media Player.
Go to the Control Panel/Folder Options, and on the View tab, set the options
so you can see hidden and system files. Specifically:
Enable (check) "Display the contents of system folders"
Enable (check) "Show hidden files and folders"
Disable (uncheck): "Hide protected operating system files (recommended)"
I also recommend that you disable (uncheck) "hide extensions for known file
types".
Then, open Windows Explorer from Start/All Programs and go to the
C:\Windows\Inf folder. Locate the wmp.inf file, right-click it and choose
install.
You may need to either insert your WinXP CD or know where your I386 folder
is located on the hard drive. You may also need to know where the
\ServicePackFiles folder is (usually under the Windows directory).
