You're not very clear as to what you're trying to accomplish.
I have my complete blog files from the blog I use.
But i started with media temple and started up a blog there, but it's blank.
Blank as in you never wrote anything or blank as in you never successfully installed WordPress?
I can't access the files from a browser of my old blog and i want to bring over the data.
Again -- what files? You're gonna have to give more details as to what you're trying accomplish. If I were to try to guess, I'd guess you're trying to move your blog to a new domain/host? If that's the case, you need to backup your database and then follow the instructions here:
However, if your site is blank what exactly is there to move? If there's a preexisting problem you should fix that before you move the blog.
