Thanks,
Your help will appreciated!
If anyone runs into this problem then check your coin daemon settings. 

I got it because my client didn't find any nodes to connect to. I found a list of nodes and added them in my COIN CLIENT SETTINGS. 

I.e:

addnode=xx.xx.xx.xx


Restart the client, run client-cli getinfo to make sure you're downloading blocks. If it works you should be seeing  

ERROR mining __init__.setup # CoinD downloading blockchain... will check back in 30 sec


Let your client update to the latest block and everything should be just peachy.
