Rob,

As far as I know (and I should), the only jreceiver config you need to do is the "Set up JReceiver User" step in the tRio install instructions. Other than that, all the playback settings etc. for tRio are set in tRio (and not the jreceiver web pages).

As everything else seems to be working, I don't think this jreceiver error you're getting is a real problem

Cheers
Paul
