Stuck on 10122 here for hours aswell.
MN setup under Windows is also a mess.
"Masternode outputs" Returns empty and the TX id from the list isnt working for me too.
I can start that shit but it switches back to missing after some time.
Back to the board devs.
If
masternode outputs returns an empty collection, the transaction was probably not exactly 10M or simply not confirmed yet (probably due to the lack of new blocks?);
If you masternode registration expires after a while, the masternode is not running/pinging the system. When you start it (the button didn't work, so
masternode start-alias {name}), check the masternode
debug.log, it should say something like 'Enabled!, you can now close the cold wallet'. After some time, you will see it pinging the system.
