Welcome to the community. Honestly, I wouldn't touch Redragon mice & keyboards with a bargepole. They are cheap, poorly made and tend to have problems with XIM APEX.
What I would recommend instead is a Logitech G203 mouse and a cheap Logitech keyboard for roughly the same price with far better compatibility and performance.
If you've got a bit more to spend, ditch the kb altogether and get a Razer Tartarus for better console game ergonomics (easily mapped d-pad etc) and a smaller desktop footprint.
