hl2.exe has stopped working on all my steam games which kind of sucks help!
All i remember doing when this happened was using windows update because it was broken and i fixed it and downloaded about 42 updates. i tried to do a system restore and it didnt work. i think it is a firewall or something blocking it if you know anything about it please help + video
