Can't play this game

I buy this game, and can’t play.

Steam Required!
Please make sure steam is running and you are logged in first

Re-installation game and Steam not help

I discovered that the problem is related to Comodo Internet Security. Disabled the comodo and worked after that.

What was the detected issue (file, specifically)?

@Gaax glad to hear you got it figured out! Hope you’ve been able to play!
