Borderlands 2 only 1 screen working

[ChronoTriggle]

Im trying to play borderlands 2 with 2 player, keyboard + mouse and a xbox one joystick, but the screen with the joystick doesnt work, I get a "fatal error addres = 0x1 (filename not found)". The screen with the keyboard works just fine

Exactly the same issue here. Worth noting that I can run multiple Borderlands 2 instances fine, just not using this tool.

Can you run multiple instances in one monitor using NucleusCoop? Splitscreen?

I get the fatal address error in the screen that is using a controller and got stuck after the nvidia logo. This happen ONLY when i use a controller, and if I use 2 controllers, I get the error in both instances. In trying to play splitscreen in just one monitor. Thanks for develop this amazing tool! If u need help, i can try to help, i'm developer too.
