Can't play since the last update

[Juniclem]

Hello,
Since the new update, I can't play Trackmania stadium via steam or via maniaplanet. When I launch the game on steam, steam says i am in the game during 3 seconds and after nothing happens. And when i launch manaiplanet, it crash instantly. I tried to uninstall and reintall the game and maniaplanet, to restart the computer...
Moreover I think I lost my logins because it has been a while I play the game and my logins were recorded in maniaplanet. I can't then connect to the website with my maniaplanet account. I tried to reset my password but nothing happens. Maybe because of a wrong e-mail adress but then i can't remember the good one.
Can you help me to solve these problems ? Thank You
