According to DashNinja, your last payment was 3d18h17m14s ago.  So something is happening to your payments.  Now I don't know what it is, but the first thing that comes to my mine, is are you using masternode.conf?  If so, are you still using the old donate to address option?  That no longer works, perhaps it is causing trouble? 

Sorry if I can't come up with the right answer, but I thought it was worth a try.  Something is definitely happening to your payments because I don't see it arriving in your account number, yet DashNinja shows it was paid.  Strange.
