As the title says, the 4306 can see my music collection served by WMP and I can see and select a track but the 4306 simply goes into a loop saying connecting 30%, 70% 100% etc but doesn't ever actually play. I have left it about 10 mins hoping something would happen but nothing does. The unit is networked via homeplugs and works for internet radio just fine. Interestingly, I have a 4308 aswell (don't ask) but that does play. Any help would be much appreciated.
