Can you see your node in the Crave Network Tab? If so does it have a uptime?
You could give me your node PubKey so i can check it on my side. Also validate if the node stays up in the "My master nodes" tab, make sure to update the form first with the update button.
Also there's alot of nodes online right now (450 at this time), so if you have a single node you have about 1/450 chance to be selected at each block. Today we had around 830 blocks, so as you see you should on average hit around 2 block per day (check http://masternodes.pro/stats/crave for more stats)
Don't forget there's the luck factor, so its not a sure 2 blocks per day, you could have 4-5 in the same day and none for a few days. Just hold on!
Good luck man!
