WPMU Dev SEO plugin is having a SEOMOZ error.

The WPMU DEV SEO plugin was working great before I upgraded, but it appears that the dashboard widget is broken? On step 4 of the wizard I have SEO MOZ scores and everything looks good, but on the dashboard widget I get:

Unable to retrieve data from the SEOmoz API. Error: .

I had this once before on a earlier version of the plugin, but that has been fixed for quite some time now and its weird that it seems to be working on the rest of my site and is only giving the error on the new widget?
