Endnote has suddenly stopped working

Hello all,

I was using Endnote (v6) with Word and Windows 7 (64bit). Everything worked for a long time, but I’ve recently applied some long overdue updates to Windows. Endnote stopped behaving the way it had before the updates:

Previously, Endnote inserted the citation (Smith, 2015) and included the full citation at the end of the document. Currently, Endnote inserts {Smith, 2015 #100) and does NOT include the full citation at the bottom of the document. 

What have I done, and how can I regain the functionality of Endnote?

Thank you!

thank you for that reply!

The ribbon is present in Word - where can I find the CWYW function? There are three sections: Citations, Bibliography, and Tools. The style in the Bibliography section was NOT the style that I selected in Endnote, so I changed them to match - still same problem.
