Alignment Problem with Corporate Theme

Anyone help with this problem:

I have installed Corporate theme and all is working well but have added the bp Albums and bp Events plugins from the Buddypress site.

I have fixed the Albums alignment problems so that it seamlessly integrates with the Corporate theme but I can't seem to solve an alignment problem with the events plugin using the Corporate Theme.

What do I need to change in the theme code to get the main part of the page to sit neatly with the side panel? At the moment, the side panel is dropped to the bottom of the page. Is it a CSS problem or a missing table problem? Or something else?

Any help greatly received...
