''Program error, verify the program has all the latest updates. If updated try reinstalling the program. If you continue to have the same errors contact the software developer''.
Have you updated Microsoft Office lately?
If that fails to resolve the problem, before uninstalling and re-instaling Office, try this usual suspect, ''Normal.dot''
Use your Search to find all instances of Normal.dot on your computer and delete them all. Word will rebuild normal.dot the next time you start it.
If that doesn't work, I think the last option is uninstall, re-install Office.
I hope this helps.
