Hi,

I've had exact the same problem. Also, every now and then I would get a DAE -1115 error.
Believe me when I tell you that I've tried everything...I just couldn't get it to work. After 3 days I got to the following and untill now, I haven't had any problems at all:

Install the Dualcore Hotfix and AMD CPU Optimizer.
Go to your BIOS and turn OFF Cool 'n' Quiet.
Go to Add/Remove Programs in Windows and uninstall (or don't install if you're about to) the AMD Processor driver (the driver to enable Cool 'n' Quiet).

I hope this will work for you. If not, say so, maybe I can help you out with my 3 day expertise in Pro Tools troubleshooting

Good luck,

Tom
