Is there anything wrong with this sgminer command:
sgminer -k qubit -o stratum+tcp://stratum.pool.mn:7823 -u Weblogin.Worker -p Worker password --difficulty-multiplier 256
That should would fine. Are you going to run purely command line or do you have a conf also? Because if your running pure command line, you will need to put other flags in there also.
No just command line, can you please correct it, it somehow doesnt work, sgminer (cmd window) pops up for a mili sec and goes off.
