Can't launch AOE2 DE

Hello guys, i can see a lot of you guys had the chance to play the game (even if it’s not liked by everyone). I would actually love to be able to make my own opinion but right now i can’t even launch the game !

When i launch it i see my status (on steam friend) changing from online to playing AOE2 DE then goes back to online not even 1 second after. The game doesnt launch and i don’t have any error message.

Any idea ?

Edit : forgot to say anyother game i have is running fine, including AOE2 HD
