Thanks - did all that, no change.

I -immediately- get the 'could not create wave file' error, and combined with the immediate 'no go' circle 'n' slash icon when I click on the track to drag it, suggests to me some issue in BIAB, not in the DAW (just in case I have tested it in Reaper, Sonar and the demo version of Studio One).

Quite stumped....
