did you update the game recently? have you tried restarting Steam and your PC?
i have tired restarting multiple times. Maybe it is updating i need. Well i currently have super slow net so i will wait a few days until it comes back nand give it a try.
but updating shouldn't be the case, i want to play without updating required so that is a problem when i cant play the game because it needs updating and what happens if i have no net, i cant play at all.
Of Course That's Just My Opinion, I Could Be Wrong
