I'm testing my whole caboodle with a Lion partition again (10.7.4).  Right off the bat, I have a big concern.  FontExplorerX is reporting that most of my thousands of fonts are missing a font file or damaged  They show up on my Library list in red.  There's no preview of the fonts where there used to be in 10.6.x.

This is an impediment to using Ae for text graphics.

Does anybody know what I can do to get my fonts to work again?

I'd rather not re-install all of them from scratch, if possible, because I've created a few dozen custom sets already, and that takes a lot of time. 

TIA, 

Jim C.
