After updating to OS 10.2.3, my Apple Profiler won't work! It just gathers and then does an error and then it quits. Maybe its not 10.2.3, ..would it be the USB hubs i have on the computer? i dont know. i think it is 10.2.3. I've tried taking the USB hubs out. and it still doesn't work. I haven't installed any new hardware... does anyone have this problem or know what to do about it??
