Same issue here...happening with the algos neoscrypt, groestl, myr-gr. Tried ccminers 811 and 2.2-skunk.
Sometimes I have to restart it 8-12 times until it works...sometimes it just won't load.

Anything we can do on our end? Perhaps mess with the difficulty or intensity? Or is this out of our hands?
