Was ABN turned back on recently?  I was mining fine for a few days without any ABN errors and then I get this error when I getmininginfo:

(Create Transaction) Insufficient funds.::TargetWeight=1995, UsingBBP=408.00, I=25, NeededWeight=1000, GotWeight=0.00; Unable to Create ABN: CreateABN::Fail::(Create Transaction) Insufficient funds.::TargetWeight=1995, UsingBBP=408.00, I=25, NeededWeight=1000, GotWeight=0.00; ",

Thanks!
