This is on windows.. all maded like it's on instructions...
you are staking only, disable staking and/or keep wallet locked. Don't unlock your wallet for staking if you want to use as masternode.
Create a new Nucleus node and use coin control to send 25000 exact to the new address. (can also set change address to keep it tidy). after 15 confirmations you can try again, enter masternode start (yourpass).
thanks for info dude! that was no mentioned in instructions!
