What do you mean by 'it fails' what does/doesn't work?
It connects, but all submitted shares are rejected.
It's not the pool either. I am using my own pool for testing in addition to testing other parties pools.
I can download the source from PPcoin and connect to it just fine, all submitted shares are accepted and an occassional yay!!!
But if I download the source for zetacoin, and preform the same process, share get submitted and then rejected instead of yay!!!
