New to gamez

I jsut recently followed the isntruction on installing Aion to start palying on this server.
I instaleld from the given site, made sure i had north america chosen.
I installed the game launcher from the gamez site
Now when i click the launcher it keeps saying verifying files so i cclick play anyway .
But i noticed i have Aion 2.5 and not 2.1 which is what the site has on the main page.
And when i try to connect to one of the two realms east or west cost it just says no authorization of server.

Does anyone know how to fix this by chance?

 

Use the search button and type in downgrade from 2.5 or maybe someone can post link since im on my phone anyways welcome to gamez and best of luck to u <3
