Lost Sprint Music Store

Was wondering if anyone else has had a problem with Sprint Music Store. I have the HTC Touch with the wm6.1 update, recently downloaded tf2d and since then, I have lost the music store. When I try to open it, I get 'jeodek' is not a valid Pocket PC app. When I try to reinstall it, it will not reinstall. I've already done a hard reset once and it was back for a day or so, then the same thing. Any suggestions
