I am having the same issue. If I travel token to a large area I can access the banner, but I also live in a smaller city, and I just get a endless loading screen after I click the banner when it's at my location.
Try a program like Fake GPS and set your location somewhere else. That should work.
Once you run the program, set your location to any city (ideally in North America/Mundus Novus if you wish to go for the Travel quests, as being out in Japan can cost a pretty hefty sum of Travel Tokens).
Then go back into Life is Magic. If the loading icon goes away but it looks like you're just floating in the clouds, go into your Profile (click on the Red Arrow at the bottom right, select Profile) and then exit out of the Profile. It should refresh your location.
