That's what's happening to me too - which is why I wrote to their technical service - and of course, have heard nothing. <sigh> They seemed to upload fine. They're *there* ... but there's no sound on the player. Don't know why. And apparently, they chose to feature my profile today. Whoopie. Would have been nice if I actually had something online for people to *listen* to when that happened.
Ah well.
