hello, ive registered supernova set up my miner and made a bat file.  when i run minerd i get the message "stratum authentication failed".   havent mined for a while , not sure where my error is?
You're not authenticating right..
a sample .bat would be:
minerd.exe -u pinkie31.workername -p x -o stratum+tcp://axiom.suprnvoa.cc:2838 
you're probably messing up the "-u" part .. many people simply put in their username there but forget the workername
