For some reason Logic 6.4 has started crashing after launching, about 5 seconds after any session is opened. I've tossed the preferences, repaired disc permissions, unplugged any external devices, booted without core audio... nothing works. No changes have been made to my system in any way since last night when it was working just fine. I have LP 7 in the box and have just been waiting for the right moment to upgrade. Is this the time? Or can ANYONE help me to actually locate the problem. I am running 10.3.9 on a 1.33 GHz G4 powerbook.
