I purchased GSX Level 2 when you had your Sorrywearelate sale. I received a confirmation email with the activation key. I downloaded and ran the latest installer (which should include the latest update). But every time I open the sim and go to the Addon manager, it says GSX Level 2 is in Trial Mode but it won't let me activate it. I click on "Register Serial" and the window goes away and its as if I have the same basic GSX that I always had.
How do I fix this?
