Alright, I need your help big time on this one. My studio pro worked great for the first few days while I learned the ins and outs, then I tried to import files, it crashed, and now it has become useless! Every time I try to import (and some times right just right after it starts up) DSP crashes with a type 2 error or freezes with a address bus error. I have tried the following: reinstalling on both drives, trashing the preferences, and turning off various extensions. The real kicker though is that I tried it on my old imac, and it works like a charm! I have a g4 733 with 2 60 gb hard drives and 256 mb ram. Thanks a lot for your help
