when i open track mania 2 stadium this happens. If i cant play the game shouldn't i get a refund i dont want to do that.

i already installed the games on steam so i should download the standalone from the website. When i also tried activating my steam code on the player page it doesnt work.

I recently bought trackmania 2 valley , and lagoon as well as stadium and i cant play them. I get an error when i try to activate my steam key on maniaplanet it says its bound to another steam account and track mania 2 canyon works fine. You can even check my steam profile this is proof i own these ...
