defender was giving error message

Hi,
On the ruhglobal.com site I was using defender and was getting the following error:
The provided domain and api_key combination are not registered. Please install the WPMU DEV Dashboard plugin.

Try again

I uninstalled and reinstalled and got it again but this time when i clicked try again it began the scan. Can you please go in and verify everything is ok with my defender install? I have support access on. domain: ruhglobal.com
