Hello
Your transaction has been declined by Mojo network, but not by us. We got the next error for your transaction:
Error: The transaction was rejected! This might happen if some of the coins in your wallet were already spent, such as if you used a copy of wallet.dat and coins were spent in the copy but not marked as spent here.
P.S. Please check that you use wallet from new network. If that's the case, please contact Mojo developers with this explanation and ask them to clarify your issue.
P.P.S I have downloaded 2.1.0 wallet....
