Hi, thanks for your help with this, didn't work first time, ran with dbug and it crashed. Nothing to do with MC32, It was hardware. I've built a custom player, fan-less with separate linear power supply's for the drives and main board. I have striped down OS and MC32 on a small drive and my FLAC files on a 2tb drive. Turns out I had a dodgy connection to the power supply! as soon as that was fixed I started again with a clean install and it worked a treat, no drama.
Appreciate the great support. Mark
