Help with initial installation?

I installed this plugin to replace ‘Simple-Staff Plugin’ and to my dismay when installed and only placed the first 3 people in there the plugin spits code and random sized images all over the page and has completely destroyed my sidebars.. Please someone help me, I have over 200 members that will be added into this system and bio’s keep rolling in.

I’d really appreciate it if someone could take a few moments to tell me what went wrong or what I did wrong..

Thanks!
