Installation says "successful" but links are dead

I've installed Omeka on my website, gone through all the steps. I'm looking at the "success" page. will show you what I mean. None of the links work now to get into the admin page. Help?

Hmmm, that's definitely strange. Were there any error messages or anything like that during the install?

It looks like Omeka's detecting that it's actually not installed, so trying to go anywhere just kicks you to the installer, which is convinced that you're done. If you look at your database, I suspect you'll see you're missing some tables.
