Rebuilding Font Book and Word

[RevJar]

I just installed an SSD on my MBP and copied over all my fonts. No problems. Now, a font that is heavily relied upon for work is listed in Font Book but not showing up in Word. In fact, less than half of the fonts that are in Font Book show in Word, including this much needed font. How do I get Word to rebuild the font index to get my fonts to show again?
