Program Error in new install w/FontAgent Pro

Just built a new Leopard 10.5.4 system on my new 2008 Mac Pro 8 core, got my CS3 apps installed & activated. Opened up my first file in Photoshop, fooled around a bit & closed it. Everything fine, but the file needed a font that was not installed. So I opened FontAgent Pro & installed the CS3 plugin, reopened Photoshop to see if it would load my font automatically. FAP tried to load the font, but was cut off by the Program Error dialog. Tried a couple more times to open this file, no dice. This is a brand new Mac, virgin Leopard install, 10 GB RAM, no reason I can see for this error. Your suggestions would be most welcome.

Gary,

Just out of curiosity I looked at my Photoshop CS3 Plugin folder and found two FontAgent plugins: FontAgent Pro.plugin and FontAgent Pro Helper.plugin. As my auto activation works without issue I wondered if you had both plugins installed?

Update - it looks like Photoshop/FAP have settled down & decided to start working right. I opened a few more files containing the font in question -no problem.
