WMP 10 gives me a 'Cannot play file' error (Error ID = 0xC00D1199, Condition ID = 0x00000000) for all media files (mp3, video).
I have the divx codec installed and these plugins installed - audioscobbler, lyrics, windows live messenger and nero fast-burning - none of which are enabled.Windows Media Player cannot play the file. The player might not support the file type or might not support the codec that was used to compress the file.
Have not installed any new software recently. Have tried deleting the library and re-scanning the hard-disk. WMP 10 does not appear to have a repair option.
Also had a problem with FTP surfer (it could not find the program files) and had to reinstall it. May not be related.
