Same problem here. After upgrading to Endnote 6.0.2 no luck. Endnote 6.0.2 works fine with Pages 4.3 but not with the new pages under OS 10.9. All endnote options in the menue are greyed.
Ah, that must be frustrating. I'm using X6.0.2 with Word (2011) on OSX 10.9 without any problems. I don't use Pages so I'm not sure what the problem is.

Download the pages patch from the Apple support > downloads page that fixes this specific problem. You have to get it manually as it won't appear in software update.
