... File is not in distributed.net client format....

The WU on the PC is corrupted, so cant be read, or the AMD driver is corrupted and cant read the file properly. How many of these have you had?

All of the WUs were doing this... I think it was a driver issue.. doesn't look like the ATI driver likes swapping out various GPU apps. Did a reboot and project reset and the WUs are crunching away now.
