Can confirm the same here – upgraded and site does not display anything further than the NGG Gallery thumbnails section – remainder of site does not display and thumbs do not display. Reverted to 2.0.66 and site functioning normally.

Always makes me wonder who programs this plugin – ever since the original owners sold out this plugin is nothing short of a pain in the ass to maintain. Every update i’m left wondering if it will completely destroy my site.

I had the same problem, in both browsers, IE 7 and Firefox 3. What resolved it was making sure I was logged out of every instance of the WordPress Admin as I had multiple blogs as well. So log into every admin panel of every blog you run and log out of them, then log back into the blog admin panel you want to change the theme on, and it should work.
