To the Nicehash guys:

I was able to get mining going with the GUI by deleting the parameters related to clock/fan settings in the json file.  I am using msi afterburner anyway so I didn't test individual components, I just deleted it all.

Also, while mining, the miner would only display something and the GUI would not be frozen *IF* I used the "--text-only" flag in the algorithm parameters in the json file.  I believe this is because I don't have anything connected to the fan header since I am watercooling.  I remember this was an issue for me before, where the miner would only display anything if I used the --text-only command...it would mine, but the miner window was just blank.  Maybe you can put that "--text-only" command into the settings page for your next release?

Hope this helps with subsequent versions of your program.
