I am not on the spotter network, but I maybe able to solve your issue. On the toolbar below, right next to the play button should show your location. If you are on your laptop, I believe it has to used another device to show your location like your smart phone or link your GPS device to the app. If you chose to use your smart phone, just have the app open both on your laptop and smart phone and it should come up with no issue. I think for the GPS device, you will have to input information from the GPS into RadarOmega.
I hope this helps.
