I just tried dwarfpool mined for two hours
Earned nothing?
Here's my bat file
ZecMiner64.exe -zpool zec-eu1.dwarfpool.com:3333 -zwal xxxxxxxxxxxxxxxxxxxxxxx -zpsw x -wd 1 -r 0 -i 6

I appeared to connect just fine and I saw my accurate hash rate displayed along with shares found ...but no earnings?
