Thanks Parky - but that's the MD600 manual. I'm talking about the MS600.

In any case - everyone can relax now and resume normal programming smile
I pulled the entire network apart and reassembled. Everything is now back to normal.
There's a part of me that would love to know WHY it stopped working, but I'm just relieved to have music!

Cheers
Mark
