Hey.
Just tried to get gminer working on nicehash.
apparently, the -pers string should be as below, not set to auto.
everytime it ran, the following error would come up.

personalization string should be "Beam-PoW"

changed it to :-

--pers Beam-PoW


and it started mining.

not sure if this needs fixing or nicehash has to fix their end.

leave that up to you.
otherwise, thanks for keeping up the great work.
