Cpm Es44acc Brake Handle Not Working After Searchlight Sim Gevo Installation

I applied the Searchlight Sim Gevo sounds and now the brake handle on the Canadian Mountain Pass ES44AC units will not function with the keyboard. I have to use the mouse to apply the train brakes. Has anyone else experienced this and if so what fix did you apply to correct the issue?

 

I would ask Searchlight support instead, they're usually pretty quick during business hours.
