I have the same problem. Can anyone help?
what error does it show?
Just open is close then
I already posted above, that use a screen recorder to recors the error and then review the video and see what did that cmd console show before closing.
you need write word - pause, in your bat file, and you see error.
minerd -a --scrypt -t 6 -s 4 -o stratum+tcp://aikapool.com:7900 -u UserName.WorkerName -p WorkerPassword
pause
my error
minerd: unknown algorithm -- '--scrypt'
Try `minerd --help' for more information.
