font Titillium

I have a problem with the fonts Titillium...

Hello people!

Yesterday I had just downloaded all the seven fonts Titillium from the site Campivisi, I copied them on the past Fonts of my computer, but I've a problem yet. After having downloaded them, at Word 2007, notepad and Paint Seven, I found only ONE font Titillium, and not all the SEVEN fonts. How do I correct the error? I'm desesperate!

Good week!
