etherminer, qtminer all works ok.

But the Claymore v2 doesn't work.

However, on ETH and DCR mining, i am getting very good results on ethermine.org with no invalids.
DCR however gives me 8-9% invalids -- but this is probably due to zpool stratum which I mine DCR,
because other DCR pools, reports lower invalids %

I have replaced qtminer.exe on all my rigs with Claymore's DM v2, even at dual mining mode I am getting very stable performance from my 390s.
