I am trying to access the Kuler panel in Illustrator CS3 (mac OSX 10.5.7), but when I open the panel (window > adobe labs > kuler) all I get is the "unable to connect to kuler service" message. I vaguely remembering needing to install something (plug-in?) in order for it to work, but my internet searching has revealed nothing. Any suggestions?
You don't need to install anything else.
Try refreshing the feed or selecting some other feed such as most popular or newest.
let me know if there are still issues
