Ok, have checked all hardware and drivers up-to-date. Saffire Pro MixControl removed re-added.
Dim Pro still at 32 bit however.
I'm thinking the Pentagon Load patch crash might be a red herring. Can someone try and open the following patch in Pentagon?

Been focussing on this issue and haven't tested if I'm still getting the transport won't stop and stop button being greyed out!
