this error is because there is sgminer.conf with undefinied pool, just rename this file to sgminer.co or something else if you use your own .bat file to run.
btw this miner work fine for me, everything is ok, and with -I 18 I get 7970 = 3,350 Mh, 7950 = 2,950 Mh

Thank you Kocurik, it helped. I forgot to delete sgminer.conf file :-)
