I have a wired Xbox 360 controller I use for all my controller needs when playing a game on my computer, Fallout: New Vegas included. Recently, while playing New Vegas, I accidentally unplugged my controller for around half a second. Now ever since that happened, New Vegas completely refuses to use my controller or even acknowledge that it's plugged in.
My controller is still in working order as it works in all other games I've started up. The issue with New Vegas still persists after restarting the game/my computer.
How can I get Fallout: New Vegas to let me use my controller again?
