People who is having trouble with pools, try a p2pool, better payments and lower fees.

First find a node near to you (ping t check latency and choose the lowest)

Then connect to the node using the ip/address plus your wallet address:

Ex: vertminer.exe -o 95.51.143.9:9404 -u "your Gpucoin address" -p xxx [vertminer settings]

It takes sometime to start seeing payments, in our case 30 to 60 minutes.

One Important thing is NOT to use an exchange wallet address, download your own, you will receive a ton of payments since you don't decide when to withdraw, instead you receive a payment per block. This means you may have to wait days if you send them directly to an exchange.

Also by using p2pool you avoid the 51% network problem, since is a decentralized pool
