http://www.google.com/search?hl=en&q=r6034+%22word+2007%22 finds several identical cases, but the ones I looked at don't contain a solution.

What I should do:
- Delete the default template (normal.dot)
- If that doesn't help contact microsoft, as suggested by the error messages (that's the applications support team, and a big team it is). If it's a recurring problem (as it seems to be) they should find out the cause and put it in their knowledge base.
