I am running Digital Performer 4.11 for Panther on a Blue&White G3 (900mhz,1GB RAM), also using a MOTU 828 mkII.

Everything installed properly, and the firewire unit sends a signal to the software, and also to my monitors, so that seems fine.

The problem is that when I press the record button after enabling the desired tracks, the cursor turns into the swirling rainbow "thinking" symbol -- and stays there forever, never recording anything. Strangely, everything works fine with files I used weeks ago, but not on new files. I tried to re-install everything and the problem persists.

Also, I cannot open any files I have recently saved -- a message displaying "error - 103" appears.

Any advice? I haven't yet consulted MOTU support as I thought someone may have encountered the same problem.

Cheers.
