Macro issues with Word 2013

I have EndNote X7 (Build 7705). Since I’ve upgraded from Word 2010 to Word 2013, I now see the following error message when I open a document:  “The function you are attempting to run contains macros or content that requires macro language support.”  This message appears three or four times.  Once I’ve got the document open, cite while you write works fine.  When I close the document I see the following message: "Want to save your changes to “EndNote Cwyw.dotm?”

I’ve tried changing the macro security settings in Word and I’ve made sure that the EndNote cwyw add in is enabled.  Neither of those changes made a difference - I see the same error messages at the same times.  Any ideas what I should do to fix this problem?

Googling this error, I found this suggesting that VBA may not be correctly installed?

I found this too  "" – which may be a solution?
