The program will stay in Trial until you activate it. I assuming your report ( "everything is loading in the menu " ) is accurate, which should result in GSX displaying a list of the Trial airports when started.
If it's doing that, there's nothing to fix, and it's just running in Trial mode, which simply means you should activate it. Since you haven't indicated any errors or issues while activating, it seems your problem it's just that you haven't even tried to activate.
If, instead, you have tried to activate, then please describe what's happening, or any errors you see on screen.
