Yep, same problem here. I downloaded today the last version of crowdrender. No GPU rendering with both computers set on CUDA only. I also tried different combinations with CPU and GPU but no luck. I render faster on one computer using only the GPU than 2 computers on CPU. I run Win 10 on both computers also. System is up to date. I really thought is going to cut my rendering time in half this add-on. Setback. Not sure why is that.
