BlogsMU Options - nothing changes?

So I installed "BlogsMU" and went through the theme settings - made a few changes - and absolutely nothing seems to have changed. :o( My assumption is that there is a "child theme" setting somewhere that I'm not aware of? I dunno.
I tried to read the installation instructions, but (of course) the instructions on the website are for other themes, not BlogsMU. I go through and edit the options again - and again - nothing changes on the site. I'm getting tired of instructions that don't have anything to do with the item I downloaded. It's annoying when I pay money to end up further behind AGAIN.
