[Hummingbird Pro] Hummingbird is breaking my site

I can’t get Hummingbird to stop using the CDN, which breaks my site (see attached). Each time I turnoff the CDN option it does not stay off and eventually the site breaks again. I really want to use all of the WPMU DEV plugins but I can not get Hummingbird Pro to stop breaking my sites (did it on Conotext.com too so I stopped installing it). Can I get help on this issue? Thanks!
