Resident Evil 5 Split Screen 2nd Pad Isn't Responding....

I Recently Started Playing Resident Evil 5 Split Screen On My PC.I Connect Both Controllers And Start The Patch. I Don't Know Why Second Controller Doesn't Respond To Sheva's Screen. While My Friend Do The Same And It Works Fine On His PC, What Else I Can Do To Make It Work? Here's The Video From Where I Got This Split Screen Idea:

try doing one pad + keyboard for the other screen. maybe the pads are conflicting

The Keyboard Is Disabled In The Patch. "For The Least Bugs" It Says So

Keyboard's Disabled, Only The 2 Controllers
