Can anyone offer any help with a problem I am having buring tracks to an audio CD? The problem started when I upgraded to SonicStage 3.4 but has persevered even when I uninstalled 3.4 and reinstalled my original version (2.3). I'm back on 3.4 now with no improvement. The problem happens when trying to burn tracks to CD. The burn process appears to be working as normal but only ever gets to 99% complete (display shows 0.00.00 remaining time) and then hangs. The CD cannot be ejected without shutting down SonicStage and when inserted into another CD player there are no tracks present. I've approached Sony for assistance and they have not been able to come with any useful suggestions. You guy are my last hope. ANy ideas?
