Bad getbalance implementation for the coin.

Thank you. The problem is on the side of DC where we have our servers.
We wish we could be there for you!

your post looks familiar to the email I got a few minutes ago from the miner. Did you mean hashfever?  
If yes then you are in the wrong thread  You are mining PCC - PolishCoin different from PLNc
