MS Office Addin works in Excel but not Word

Hello,

I have an odd situation.  I am using a Microsoft Office Addin called 'BI Publisher' which is an Oracle product.  It is designed to work in Excel and Word.

I am using Office 2010 on a 64 bit Win 7 SP1 machine.  The addin installed correctly and appears on the ribbon in both Excel and Word.  We are using it in Word.  It was working for me, but it has stopped working.  It still appears in the ribbon and the icons show active, however, when you click an icon nothing happens.  When you go to Excel, it works.

I have uninstalled and reinstalled the addin.  I have used 'Programs and Features' to repair Office.  I looked at the Event Viewer logs.  I am having no luck.

I hadn't made any intentional changes to the machine and it worked one day and not the next.

Any ideas on what the difference would be between Word and Excel using the same Addin?  I am a developer, but not familiar with developing in Office.  Is there a way to capture what is being executed in Office using Visual Studio or something else?

Thank you for your help,

Jer
