Did you look in the console window to see if an error was reported? If an error is reported it means that the menu item does not exist. However, I don't think you'll see this error. The menu item does actually exist and if you run it from the console window it will work. However, this menu item can only be run from a privileged context.
I'm pretty sure this was also true in Acro 9, but I could be wrong. Anyway, the fix is to "WhiteList" the menu item. On windows this is an entry in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\8.0\FeatureLockDown\cDefaultExecMenuItems
On the Mac its in a setting file.
