Mac CWYW for Word 2008 - Format bibliography - doesn't happen!

Hello,

I am writing a paper using Mac OSX 10.5.4 and EndNote X1 with the CWYW for Word 2008 update. Office is at version 12.1.2 (latest version).

Problem is: I want to reformat the paper from one style to another, selected a different output style and selected “format bibliography”. “Repaginating”  pops up and something seems to go on, but NO changes are made. I can’t (re)format this paper!

The paper was originally written in Word 2004, is this a problem?  File format is .doc [compatibility mode] and NOT .docx

Hope someone can help.
