Thanks for helping me guys, i did a fresh win install on this time.

I think i have a match between Pool Address on Cube and IP of the proxy PC, i did a screenshot, here is http://imgur.com/KSGwJ4h

I dont understand how to communicate CGminer with the Cube,i have some experiencie with mining Litecoins but nothing at all with ASICs and it is a bit confusing for me, the guide of Dogie on this website only talk about Cube's setup but dont talk about mining with it, some people use bfgminer and dont use proxy but i prefer cgminer (more trusted app i think), one more time thanks for the help.
