So what do I have to do next time?
Use this link to download most of the non beta addons - http://www.wowace.com/files/
All the files are in zip format and you just extract them into the addon folder, no need to create the folder and copy the files 1 by 1.
The addons on http://svn.wowace.com/wowace/branches/ are usually testing/betas version so it might not work properly. This currently does not have a server to let you download zip files atm.
If you still have addons using Ace not Ace2 then i auggest you get oCB from the /files server and once when oCB2 is ready you can replace it.
