EndNote X7.2 CWWY not working in Word 2013

I just upgraded from Word 2010 to Word 2013 (Microsoft Office Professional Plus 2013, 32 bit) on Windows 7 (64 bit).  EndNote’s Cite While You Write is no longer working in Word (I no longer see the EndNote tab).  I am running EndNote X7.2.  I tried reinstalling EndNote X7.2, but that didn’t solve the problem.  I also tried running the “Configure EndNote” program, and I made sure CWWY was checked, but it didn’t solve the problem either.  How can I enable CWWY on Word 2013?  It used to work fine for me on Word 2010.

Thanks in advance!

Thanks Leanne.  This solved the problem by activating the EndNote add-in under Microsoft Word options.  Thanks!
