TreasureSeeker , I have change the value to +0.00000116 because I have indeed a very low rate at this time.
Only after a little 5 hours of mining i'dont receive coins.
But the mining tool give me a positive feedback for mining.

At this time I have run 2 systems with a total of 15KH/s and have about accept a couple 100 of shares but nothing is coming in.

Is there a problem that after a few hours something stops?
