I updated to Sooloos v2.477 Build 406 and get an odd error now.
Some songs it plays just fine and some stops at "loading" forever. Can't get it to play certain songs no matter what.

Main: Marantz Cinema 50, Meridian 271, DSP7200.2, DSP5200HC, DSP5000 rears, Meridian 210.
PC/Headphones: Mytek Liberty II, Sansui CA-F1, Sansui B-2301, Sennheiser HD800, Kef R3
