Ok, just bought the game (like, right now...). Been trying it for the weekend, and couldn't login to my account, but thought it was because I didn't "own" the game. But now, I own it, and still can't login to my account.
Linux Mint 18.3, 64bits. Come on, Devs, I know it's not "that" important to log in to our accounts, but... is it too much of a hassle to solve something so tiny like this?
