Are you using anything like Xslimmer to remove PPC code or languages from Office?
Repair permissions?
Some preference file may have had its permissions screwed up, causing office to fail to launch.
Ill try this first. Do I have to go into disk utility for the hd and just click repair permissions?
What have you changed since the applications started crashing and before, when they weren't?
Have you moved your Office folder? Have you run an application like Xslimmer or Monolingual? Have you manually deleted something in your Office folder?

This is just a random guess, at least it can't hurt, clean your font caches.
I've had problems before and cleaning the font cache did help, but then again I have a rather large font portfolio. I use the (free) MainMenu app, but I'm sure there are other ways to do this.
