Having same issue with antminer D3 i hooked up yesterday - mined for ~4-10 hours showing correct estimated hashrate, but no unconfirmed or confirmed reward showed.
I got the D3 in early Dec and tested it by mining .02 dash on coinotron and that worked then - disconnected it til i could get a hold of some sound proofing to quite it, now rerun and nothing showing in confirmed or unconfirmed.
Hi
It is a matter of mining reward you choose.
Your workers at Coinotron are in PPLNS or RBPPS mode, therefore we don't show current round rewards. Right now pool's hashrate is quite small, so we are finding blocks every several hours.
When we find next block pool will calc your reward and update your unconfirmed balance.
To get stable flow of mined coins please switch your workers to PPS.
In this thread you will find very good explanation of how PPLNS works:
