look at the second-to-last response in that thread - it may help....
I had a similar problem today after restarting Win7 on my laptop. When I checked the fonts (Start button --> type "fonts"), I realized that all of my fonts were missing besides unicode. I transfered all of my fonts from my old laptop to my new laptop that had the problem, and everything went back to normal.
(FWIW, my registry doesn't have the stated Key either, in Regedit)
