I think Sparks is correct. Try putting the files in a folder called C:\Songs or something like that, and then see if they will play. I think there is a Limit of 256 characters, for the Folder names and the Filename. So if you have it in some long folder such as C:\Documents and Settings\Bryan\My documents\My Music\Alan Jackson\Where were you when the world stopped turning.wma. Then you would have a problem, as we have looked into this, but this seems to be where the problem lies.
