I downloaded Quicktime a few days ago and it bumped Window Media Player out of the default, despite I denied Quicktime's request for being default.
Found that out when all the music bars showing Q but wont play.
I reset Window Media Player back to default (took some search and guessing - not easy to figure out in the Window Media Center OS!). All musics now play, except yours.
The version of mine is 10, does it make any difference?
thanks.
