Nun Pad doesn't work

I’m using the Lambda menu and the num pad doesn’t seem to work. I haven’t tried any other trainer so if you guys could let me know of others I’d appreciate it or if you guys know what’s wrong.

Do you have Num Lock enabled?

It works on like Google and stuff but idk if I do or not

There is a key on the top left of your num pad. It says Num Lock. It will turn a light on your keyboard on or off when you hit it. Make sure the light is on.
