Thought I would try you to get some advice. My system is very, very unstable w/DP3. I cannot open DP3 without it crashing and freezing my Mac. I have been rebooting it endlessly. Do I need to trash some prefs? Do I need to move something around? 1024 of Ram. Where should I look for the problem. I have been on the ph w/MOTU 5 straight days since I bought it last weekend. Any advice would be helpful. I am very envious of all of you who have been running DP3 seemlessly. I would like to say it was a good program but this is ridiculous.
