So my dock has been having issues ever since I tried to change its background using leopard docks. It wouldn't remove applications, just "restarted" itself whenever I tried. Now following other posts, I deleted all of it contents, then tried to reinstall it. Without sucess. Now when I try to open its file (system -> library -> core services->) It says it cannot be opened because the system doesn't support its architecture. Help! I want my original dock back!
