citations updating but not reference list

I am able to insert citations into the text, but I get a ‘command failed’ error when it tries to update the reference list. If I ask it to update the references, I get this same error. Nothing has changed, endnote was working perfectly for me yesterday. Any ideas on how to fix this?

Have you tried converting to unformated citations (after making a copy of the existing document)?  If there is a corruption, after you do that, select all and remove field codes then reformat and see if it works now.  

Here is a short walk-thru, but it is also in the knowlegebase under support at somewhere (I don’t usually need to copy to a new document though).

Here is a link to the article Leanne mentioned:
