Not Working Correctly

I’ve been trying to get this thing to work. I can’t edit the colours of the bar, the register function doesn’t work (or I don’t know how to set it up), and neither does choosing an avatar, it comes up as a broken image when you change it. The drop down menus look nothing like is shown in the screenshots. I already have the bbPress forums set up, but how to I utilize this Social network thing? I can’t find any useful options to customize or add anything… I need some support or some kind of instruction to use this plugin…

Any help would be greatly appreciated.
