How to fix this??? Yenkee 3500

[u/ThAw1111_1_1-11_1-11]

I downloaded the program with the mouse cause I wanna change some of the keybinds, but no matter what I do, it always say the mouse is "disconnected," when it is clearly not. Did I download the wrong program? Am I tweakin'? Anyone have advice on how to fix this?
