A plugin question with this theme

I have managed to get all the center columns the width that I want but can't get the calender to work the way that I want. I am using Events Calender, by a different company. It takes posts and puts them onto a URL but not a page. I can't figure out how to adjust the width of the center column as it is not a page. thoughts? I know, it's not your plug-in but please help. it's driving me nuts.
