Hi to everyone,

i've just followed the tutorial to set up a masternode (already with the monoeci wallet) on Ubuntu, but when i try to get the command "masternode outputs" it show me nothing.
I've already send the money to the address given with the command "getnewaddress 0", the transactions are confirmed (over 200).
I've tryed also to put manually the transaction ID on the masternode.conf on my wallet to go forward, but when i try the command "masternode start-alias mn1" it show me this error

{
  "alias": "mn1",
  "result": "failed",
  "errorMessage": "Could not allocate txin xxxxxxxxxxxxxxxxxxxxxxxx:0 for masternode PUBLIC_IP:24157"
}


What can i do?
