Replacing an iWeb site with a concrete5 designed site

Permalink
I have hosting elsewhere, (machighway) and they offer Concrete5 as a website builder. I have downloaded the version 5.5.2.1 but when I attempt to log in, I can't see the "edit" functionality that I enjoyed when working on a demo off the Concrete5 site. Yes, I wish I would have done my hosting with you, might have been easier... but can someone tell me why I can't see or use the Concrete5 functionality in this case, and what I need to do so I can use it?
