Hey Gerard,
Just to update you on my own progress. I had just returned from my trip and missed the official release on the 23rd of 3.2.
I too had my MBP reformatted and re-installed, but with the latest Maverick version x.3? I had 3.1 Cross and 3.2RC on there.
I installed 3.2 yesterday and it would crash upon opening. So, I went and deleted all Cross programs from the programs folder, as well as the dock icon for cross. Rebooted the Mac. Then I went and downloaded the install from the updates folder at the forum (it made it into a filename(1).dmg, so looks like the same file) and ran it.
Opened Cross 3.2 and worked like a charm.
I haven’t had a controller or external sound card hooked up yet, so can’t tell you about that. Does 3.2 not recognize your soundcard, but can you select it in output settings?
Greetinx.
