I assume the registry was messed up somehow, which broke the association
between .wma and Windows Media Player, or you added a third-party media
player, made it the defaul for .wma, and then removed it.

A hard-reset would fix it, but erase everything you've added to the
phone. Instead,you could try a registry editor, like PHM's RegEdit, and
set HKCR\WMAFile\Shell\Open\Command\Default to {wmplayer.exe "%1"}
(without the curly brackets, of course.)
