What does this (the 'disabled') mean, and how can I enable it again?
Proth Prime Search (Sieve) CPU, Nvidia (CUDA) (disabled), AMD/ATI (OpenCL) (disabled)
Can it have to do with my GTX 260 having died and replacing it with a GTX 650? I had no trouble receiving PPS Sieve WUs while the GTX 260 was still functioning, but soon after the switch to the GTX 650 WUs did not come anymore. Switched the box to other projects in the meanwhile.
