I'm posting anywhere I can find to postafter downloading several new fonts from MyFont.com, as well as cleaning out some old fonts from my external hard drive, all the text on my Mac Pro (OS X Snow Leopard) suddenly turned to the symbol for the "A" key. See attached screen shot. I suppose I got hold of one that was corrupted. I can't get into any folders on my Mac because all that appears is a blank window that does nothing. I'm thinking I'll have to take this to the nearest Apple Store and pay some bucks to get things rolling again, no?
