Blog is visible via dashboard, but not on webhost

When I click on “visit site,” I can see my blog–posts, FAQ, blogroll, everything I’ve created so far. Problem is, despite it being FTP-ed to my host, when I go to my blog (https://writingbabe.com) it still says “future home of…”

Media Temple support says this has something to do with my accidentally installing WordPress twice.

I deleted one entire installation file by file, and left the second one, which is in the correct location, where it was.

Now that I’ve done this, nothing has changed. I can still see my blog via the WordPress dashboard, but not by going to the url.

What’s wrong, and how can I fix it? The Media Temple guy said something about htaccess, which I know nothing about. Where would I find it? How do I know if it’s correct?

Any help would be greatly appreciated!
