Both are referencing cooltype.dll. I ran Font Doctor on all system and non-system fonts and found no errors. Booted without Extensis Suitcase loading. Nothing works. All 32 bit programs work fine. Any clues would be appreciated.

Answer 1

It does not necessarily mean a "corrupt" font, but can be a font that PrPro, and PS, cannot handle.
Though I have read that changes have been made, Open Office's DejaVu font would crash PrPro's Titler - every time. There are quite a few others. Font Dr, and similar utilities, will not see the font(s) as corrupt, but they are so poorly designed, that PrPro and PS cannot deal with them.
Though it can be a long, drawn out process, one can often zero in on the problem font(s), with a little work. This is accomplished by first defining the "System Fonts," and not touching them. Then, uninstall half of the remaining fonts, and testing PrPro and PS. If they launch fine, you know that somewhere in that list of fonts, the problem exists. If there is still a failure to launch, chances are good that the problem font(s) reside in that half, that are still installed. Note: because the problem still exists, does not guarantee that there are NOT problem fonts in that uninstalled group, so keep that in mind.
Repeat the proces, by uninstalling half of the remaining fonts and testing.
If necessary, repeat by removing half of the now remaining fonts and testing.
When you get to a point, where you are no longer getting problems, reinstall fonts, in small groups, testing in between. The smaller the groups, the easier it will be to pinpoint the problem font(s).
Keep notes on which fonts you are uninstalling and reinstalling, until you narrow it down to the problem font(s).
I would start by uninstalling any "free fonts," and then commercial, 3rd party fonts. A lot of free fonts are just poorly designed, and can cause issues, though they might work fine in some other programs.
I use a font manager, so that I only have ~ 350 fonts installed at one time, and then dynamically install fonts, as needed for Projects. That keeps my machine clean, and if, upon installation, I get a crash/hang, I know that at least one font in that Set is causing it. This helps, as my workstation has ~ 19,000 fonts on it, and some are free fonts, and many are from 3rd parties. Some are also very, very old.
Good luck,

PS - one common cause for hangs on loading PrPro can be from VST's, used in Audio-editing. If you also have a lot of VST's, you could have two issues with two separate programs, i..e. PS hanging on fonts, and PrPro hanging on VST's. The results would be the same, but the causes could be different. That leads to even more work. For PrPro, also see this ARTICLE. If you get PS launching, but PrPro is still not functioning, drop by the PrPro Forum, and someone can help you there.
