Help with theme, not working

Hello,

I am new to wordpress. I purchased a theme called Arliss from Blurbia. It seems the theme partially runs on Java, which I am not familiar with. There is supposed to be a rotating featured post banner that I can’t get to work and I also can’t figure out how to use the banner ad spaces that are pre-configured (I would like to put adsense code into it). In addition to all of that, I can’t seem to figure out how to make the navigation bar show categories instead of pages. Any help would be greatly appreciated!
