I was suspicious that I was using the wrong version of JEmplode as I knew there had been an upgrade for version 2 of the player software. The version I've been trying is 1.0b1 which looks as though it's an early Beta. I got it by following the link on riocar.org (takes you here. If this link is wrong maybe it needs updating. I haven't got much time at the moment (off to the GF's soon). I'll try the link you suggest and if I still have problems I'll run that debug thingy and send you the output. Thanks for your help.
