Plutonium

For some reason why controller no longer works while in the game. My computer recognizes that I have a controller connected, but no matter what I do I can't use my controller anymore. Any help is appreciated.

Thanks for the help

I'm trying to to play IW5 and I've tried by best at following all of the steps but I can't seem to find my game file when I download the dedicated server. Any help will be truly appreciated.
