I've been having issues installing fonts, in one instance I had a font installed and I've been able to use it in Fireworks but all the sudden it won't work. Font Book says it's installed. There's also another font that's apparently installed but Fireworks says it isn't. Both are True Type Fonts.

I've tried installing them through Font Explorer but still having the same issue. They have a dot next to them in Font Book so I tried removing duplicates again not working.

Is there any way I can fix this? Or should I start from scratch (how?)?
