Obviously a plugin problem, so I booted DP with the option key down.. didn't take long to nail it down to Altiverb 7, and both the AU and MAS version would cause the crash. My version, I'm embarrassed to admit, was 7.1.0, and now we're on 7.2.8!
So I updated, and everything worked perfectly! Yea!
Still it's curious, that all of a sudden, out of nowhere, Altiverb decided it was too old and quit working. There was no warning, and seemingly nothing had changed on the computer? I know Altiverb logs onto the internet from time to time because it shows me the new IRs that are available, and keeps an account of which ones I have downloaded.. sneaky little devil, that's probably how the problem started.
