Sorint Music Store not working

[onesickvdub]

First off, I want to thank all you guys for all the great content and information here. That being said, something I'm having a problem with is the Sprint Music Store. I searched on here for any information and have no luck.

Basically, 9 times out of 10, music doesn't play. (I say this because I've tried about 20 times or so to get it to work, and it's only played my music 2-3 times).

It gives me Error M506: Unable to Play Song.
file:///MemoryCard/Music/songname.koz
cannot be played.

My friend, who also has a Mogul (Titan), also has the same problem and he has the updated ROM (well, it's useless now...).

When trying to google an answer, someone suggested to try formatting the card. I did so, and it played once and that was it.

Any information will be useful, thanks in advance.
