Solved it!, the problem was that Windows Media Player was not in the list of installed windows components(I still had it but it doesnt show up in things like the start menu). I simply selected to show it and it works fine now.
lol, It took a while, and the only reason i noticed it was because it wasnt showing up in the list of programs i could use to open up music files.(which was your suggestion of opening it up in a different program)
