Vista with Word 2003

I just changed computers to one with Vista Home edition, but kept WOrd 2003. I installed my Procite 5.0.3, and it works fine. When I open word the toolbar is there, but the buttons don’t work. I’ve tried the fix from the procite website, (Manually installing ProCite’s tools into Microsoft Word.) but it didn’t help.

 

THank you for any help,

Ian
