I have been staking since a day after the presale, i was order #3

I received a few coins for the first day or so but now i am not receiving anything.

For the past 2 nights i have had about 7-8 hours to go until reward, but when i check when i wake up i have no rewards and the timer has gone up to 2-7 days. Then as i get nearer to the evening it goes back down to 7-8 hours. But nothing comes through.

What am i doing wrong?

My wallet is unlocked and nothing has changed from when i last had rewards - excpet this morning i have rebooted the machine.
