Endnote 7 tab not showing on my Word

I use Endnote 7.7.1 and when I updated my Microsoft Word 2016 when I open Word it says

"Your add-in isn’t compatible with this version of Word. Please contact the add-in provider for an update. (EndNote CWYW Word 2016.bundle)."

I have had the exact same problem in the past and resolved it my going through the customizer tab on endnote but this time it doesn’t seem to find the add-in. 

Any help would be greatly appreciated.

Many thanks!
