Game will not start (PC)


I have verified game cache, I have played the game before with no issue, I have AMD so I don’t use invidia and all other games launch and play fine. I hit play or double click the icon, it pops up in my task manager, gets to 71,600K or so and then just disappears off the task manager and doesn’t start, no error messages, no warnings, just gone. I have windows 7 and up until now, had no issues with the game.
