MC5.5.4 + Mojo + 002 problems...

With MC5 connected to an analog Mojo and the Digi 002, when playing audio in the timeline, the audio won't play through the 002 - I eventually get a 'Adm' error. If I put caps-lock on and scrub the timeline, the audio does play through the 002. These are some of the errors that I get:

20140117122516 FatalExcpt Exception: AdmAdm overrun.

The MIDI error is with a WAV file that I imported for testing. Typically, it's the 'AdmAdm overrun' pop-up box that appears. I've tried a whole raft of things from the video driver to re-installing but it doesn't work. I didn't have such issues with MC5.5.3.

Dare I take the opportunity to say that ADM_ILLEGAL_SYNCSRC is still present. We've been banging on this drum for a few years now. We are getting updates and I was hoping this would be fixed by now.

Thanks
