At this moment, if you use the Curse Autodownloader to update your addons, its not working properly. There have been numerous threads by some of the addon authors complaining about and warning people that its not grabbing the latest versions of most addons.
For the key ones we use for raiding, I suggest downloading them manually off our site if you see its been updated until they fix the problem.
I personally done use it, but Ill keep my eye out for when its fixed.
