Upgrade 2.1.4 - 2.2.1

Hey Guys,

Now that I bought the upgrade extension for a year I am having problems with the upgrade. Normally I would just click install and it would run. Now when I click install it brings me to a blank page on Internet Explorer, Chrome and Safari. I am trying to go from Upgrade 2.1.4 - 2.2.1. Any help would be appreciated.
