Hi,

You'll need to continue to work with the developer on a path forward. We and the community trusted the developer and his code put us into this situation.

You could try to withdraw your balance into an older ninja wallet and taking your chance on an upgrade. Some of the coins might be valid on the forked blockchain.

Thanks,
Bill
