Help needed queuing tracks through headphones

Know this question comes up a fair bit - I've tried to read posts and apply replies but still am not able to listen to a queuing track through headphones on mixvibes.
I have a gemini first mix usb controller for a PC - my mixvibes serial should be registered under my details.
I was actually able to get the headphones queuing on virtual DJ, but not mixvibes, so I know it is possible! I've also tried ASIO4ALL and have attached screenshots of my settings below. these might not even be close but are just what I last tried.
Absolute novice here so as little jargon as poss please! appreciate any help you can give me. cheers
