Any coin wallet will go out of Sync if no block has been found within 1 hour from the last unless changed in the source.
Generated but not Accepted to me basically means you and somebody else generated the same block but they got paid instead of you hence why you have received nothing. You will find a stake don't worry if you don't just increase the size of the staking blocks although saying that I get stakes even off 0.1 Fury and so on. so i'd say it's the first thing I mentioned two people mined the same block.
Any help or questions just ask I am here 
Thanks Thanks for the reply ... really complete
