Let's start by looking at the crash report and see if has a clue. Post it on pastebin.com and put a link here.
This report was generated when I created a new document, added a text box with serveral words and then tried to save it as an idml.
I am wondering if there is a plugin I might be missing?
Thank you very much for your time and help.
If you look near the top at the virtual memory regions you'll see a font listed with some gibberish in the name. Thats a really bad sign and a clue that you probably have a corrupt font.
Via Font Book, I checked all fonts with pro in the name. All appear OK.
I created a new document with nothing in it with same result. My crash report (http://pastebin.com/Rgd5AAHZ) was a little different under VM Regions.
Do you believe a re-install would solve the issue?
Thanks again for your help. It is appreciated.
The new crash looks like it implicates LiGothic.ttf.
Did you do all of the steps in the troubleshooting article? I wouldn't presume that Font Book validation is definitive (and it only looks at fonts managed by Font Book, as far as I know).
