WPMU Dev Dashboard breaks Zaxaa Member font-awesome icons

When I install and activate WPMU Dev Dashboard on my site, it breaks the font-awesome icons in my Zaxaa Member plugin Admin area, so that all the Zaxaa Member buttons become useless since I can't see the icons that indicate what each button does.

If I don't have WPMU Dev Dashboard installed, I get the constant nag bar at the top of the screen. I would like for the two plugins to play nicely. Is there anything I can do to correct this in the WPMU Dev Dashboard plugin files?

Thanks for your time.
