Call of Duty: Modern Warfare 3 Request

The game's old, I know, but I'm hoping you can update your widescreen fixer for the current version because I've been stuck with a HUD that's not suited for my monitor for years now after some glitch and I can't find any solution from re-installing to finding a config edit.

Even if you help me find some other solution, I'd be more than happy to pay for your time. 

Please consider. Thank you!
