So is the footer not anything to do with the CSS problem?? o-o

And 'And I'm not sure where the #profile thing is. There are so many css files in this new script...'

Just add it if you can't find it lol... just see if that works.
#profile .nav {
overflow: none;
margin: none;
}

Which file do I add it to? My style css? menu css? Sorry, I really only guess at coding. xD

I'm not sure what is causing the footer problem to be honest - I mean, the whole div is just moving and inserting itself somewhere else. It doesn't do that for any other divs.
