Can't Purchase Upgrade

I am trying to upgrade from Standard to Ultimate, when I click on the "Upgrade" button when you launch Fantasy Grounds it takes me to the below URL and it has some sort of key at the end of URL which I am not sure is safe to post or not. When I click the "Buy" button to add the update to my cart it redirects me to the store page and doesn't actually add anything to my cart. Anyone else having issues purchasing the upgrade?
