Please help! Miner is no longer working

Ive been happily mining away for the past couple months using coinotron pool to mine ETC. On friday i noticed the miner was not working so i restarted it and it just closes. If i try any other port on the pool such as the ETH one it works fine.

I use etherminer multi gpu cpu miner with a gtx 1060 oc windforce 6gb

Any knowledge into this issue by some of the advanced miners out there would be great.

Thanks
