Hey, it was a very simple "mining.bat" with the following contents;
ccminer -o stratum+tcp://xmr.crypto-pool.fr:3333 -u myaddress -p x -l 4x10
Anything below 4x10 would cause ccminer to revert back to the default 8x40 value.
post your command line, something isn't right
etc.
that equal sign matters.
