I downloaded both Mafia 3 and NBA 2k18 yesterday. Played them both completely fine. Now today the damn games won't even launch from steam! It's ridiculous!
I've unistalled, verified files, unistalled and reinstalled steam. Then games.... still nothing! NONE of my games run!

Please can someone help me! I don't want to have to wipe my pc and reinstalled windows again!
