I am desperate please help!!!

 I have several MS Word mail merge letters that link to access databases.  It have to use Microsoft access because I have some complicated querying that I am doing.  Normally when you open the word document, the access database opens at the same time.  I have a macro that runs when the access database opens. 

 About two weeks ago, the database stopped opening automatically.  Everything else still works, but since the macro in access doesn't run the data is not updated.

 This is happening with all the documents not just a few.  Does anyone have any ideas why this would all of a sudden happen.
