Upgraded to Pro?

Hello, I just purchased the upgrade to Catch Everest Pro. However, I'm confused as when I go to "Theme Options" section, the upper right corner still has a button that says "Upgrade to Catch Everest Pro". Do I have to do anything special to install the upgrade? Or can you check to see if I'm currently running the pro version? Any info would be greatly appreciated! Kind regards, Sbartsch
