The Kuler panel in my copy of Illustrator seems to be having some issues. When I first opened Illustrator today, all of my favorited and saved Kuler palettes were missing and it instead was greyed out and said there were no palettes associated with this account. Logging in through kuler.adobe.com, however, still has all of my saved and favorited palettes. If I favorite new palettes (or even un-favorite and re-favorite existing palettes) and refresh the panel, they will come back. However, I have dozens of palettes saved that I'd prefer to have easy access to without going through this weird, tedious workaround trying to track down every single one.
Has this happened to anyone else? I will say, I love having a ton of easy to access color palettes laid out for when I need inspiration, but I've seemed to always have various issues with the panel actually functioning correctly, this just being the latest of many.
