Blogger world, help?

Okay, I am about to pull my hair out from frustration.  I am trying to go through the step-by-step process from kevinandamanda.com's website for downloading custom fonts.  I have created the hostwebs page, but everytime I click on the file manager icon, it won't work!  I have restarted my computer, and it still won't work!  Any help or suggestions is greatly appreciated.
