Well, I solved my own problem. This is just too weird. I looked at the template folder, considering that I had the "hint" in the disabled items tab that there was a problem with the Snag It dot file. I saw no normal dot file. I click the folder to show hidden files and saw the normal dot file. Then when I opened Word it opened normally. When I closed it, it gave me a message that the normal dot file existed, and asked if I wanted to save the changes. I clicked Yes. Now Word opens normally.

Whew.
