@brdcphoto, Did you actually delete everything in the fontinfo.txt file, or just look for weird characters? I don't know for a fact that weird characters in the file fail to cause Flash to launch. It could also be the sheer number of fonts too if the .txt file is large enough. Empty the .txt file, save as Read Only (you need to ENABLE this option, not Disable as in your post), and then try restarting Flash. My fix works on Flash CS5.5 and CS6.
