Etc + dcr
From the looks of it you seem have some trouble on Suprnova pool
you must specify a worker name, in your config above you only have a Login name
take note of this portion
-dpool stratum+tcp://dcr.suprnova.cc:3252 -dwal YourLogin.YourWorkerName -dpsw x -allpools 1
with that, it is mandatory to create an account on Suprnova pools and from there you could also specify a worker name
