I still don't see another transaction in blockexplorers using that transaction's input. I'll be too late if you leave it that way.
If you used the coinb method, you need to broadcast it using the broadcast tab after creating the signed transaction.
It won't automatically broadcast after clicking "
send"; copy the raw Tx, click "
broadcast" tab and paste it there, click "
submit".
Take note: you need to include the specific input's tx id for coinb to know the exact input to spend (
it's in the online blockexplorers).
If that helped, you can keep the reward.
