Cite while you write error

Hi,

I normally use Mendeley but the journal I’m submitting to only has an Endnote style. I’ve got CWYW installed and everything is in my Endnote library but it won’t let me insert anything. When I click to insert a citation it appears when I search but I am unable to select anything as immediately an “EndNote Error” box appears over it. I’ve changed the properties to “Write” as per a different post but that hasn’t helped. Any suggestions would be greatly appreciated.
