Huh, didn't realize that That's quite sad. Not nice to be a GridSeed user these days, latest cgminer is not an option since it's declared as "non-scrypt" and sgminer is not an option since it's declared as "opencl-only" That leaves only two options: encourage luke-jr to incorporate GridSeed support into latest BFGminer or fork cgminer-3.7.2+upstream patches with GridSeed support and create "gsgminer"

p.s.: there are already NiceHash supported options for GridSeed users, see here: https://www.nicehash.com/index.jsp?p=faq#faqs0
