This answer only applies to the Refworks/Write-n-Cite 4 Word add-in that shows up as a ribbon in Word for Windows and a toolbar in Word for Mac. It does not apply to the older Write-n-Cite III add-in that created a pop-up box.
Have you selected an output style? If not, select an output style and try again. If you can't get the choice of a style to "stick", you may need to reinstall java (It's freely available at java.com).
I've seen this error primarily when I first insert citations in a document. Usually, if I save the document, close it and then reopen it, the error mysteriously disappears and I am able to continue working without further problems.
