endnote X6.0.2 does note recognise references in a text created few weeks ago on MAC

Few weeks ago I created a text with formatted references from endnote. I have endnote X6.0.2 and Word 14.3.6 on mac OSX 10.8.4. 

I am trying now to unformat the text and endnote can not recognize the reference. When I click on the reference they become grey indicating that something is recognised but I can not edit or do anything to the referencxe.

Any idea? 

The only thing that might have happend is that word was updated but how can I solve it if that is the problem
