Can anyone tell me why when I open a PDF file either in Mac Preview, or in Acrobat Reader and I get pages of garbage fonts. Where normal text is there are little boxes with x's in them, or just garbled letters.

I'm running Suitcase Fusion as a font management system, I seem to get the same problems on my Desktop Quicksilver running 10,3,9 and also my laptop runing 10.4.

Any help would be appreciated.
