Today when I clicked on the little windows media player icon in the quick launch bar this message popped up in my face "The file wmp.dll has a version number of 9.0.0.2980 where 9.0.0.3008 was expected.
Windows Media Player is not installed properly and must be reinstalled. Do you want to install the Player from the Microsoft Web site? "

Solution:-
The deal here is click on no, do not re-install because you will end up with the problem all over again. Goto this Microsoft link and download that little package file over
there . This will update your windows media player to version 9.0.0.3014 and also cure that problem.
