Hi, Recently I got this great game on Steam, but sadly a couple of minutes into the game (tried 4 times) the mouse buttons and escape key stop working. I cannot click anything and the menu will not appear on hitting escape. I can however move around using the arrow keys and the game keeps running smoothly. The cursor is also still working fine. Specs: i7 quad, 16 GB ram, nvidia GeForce GT 720 on nvidia drivers. If I missed the same issue already posted somewhere else, I'm sorry! If you're able to help me enjoy this game to the fullest I'll be forever grateful Thanks!
