I don`t know if it is still the same after the release of the Universal demo (I have all games, so I can`t check it), but in former times you could check it like this:
Go to the playerpage (
https://player.maniaplanet.com/account/downloads), login with the account you are using and check which games are available to download.
1) If only the Minimal setup is available, you are using a demo account and you have to find your correct old account informations to play the full game again
2) If the separate Stadium installation is available too, there is indeed something wrong with your game. Maybe try to reinstall it?
Like said, this was a good way in the past, I don`t know if it still works this way now, maybe all installations are available anytime now.
What is still bothering me, is what you wrote here:

Because if you created a new account, you need a new key for that account to play the full game, otherwise it`s demo.
