Font doesn't work in Photoshop

Hey Everyone!

I was in MS Word 2007 the other day when I found a perfect font for a title. Knowing that I'd want to use it in other formats, I opened up Photoshop & InDesign to create a larger version of it. However, Photoshop refuses to use the font (you select the font and it just disappears). I did a little research on the internet and found out that the font I'm trying to use, Gautami, is supposed to look like this:

However, I opened up the otf file and got this preview (which is what I'm looking for!)

Here it is in MS Word:

And now in Photoshop:

Can anybody tell me why this is happening? Did my fonts get switched up somehow? I'm dying to use the font as seen in the Word document :/

Thanks a lot for your time!
