Smush Pro Won't Activate

Hello,

I have been attempting to activate WP Smush Pro on my website and it keeps saying that I'm using the free version and am limited. I attempted deleting all the plugins and restarting with WPMU Dashboard and I tried installing from the Dashboard and from FTP. It says I can "upgrade" and takes me to my account to download the plugin which I then upload and still no fix.

Any ideas or support you can offer would be appreciated.
