I am currently running an older version of iWork and I can't update Pages, Numbers, or Keynote. I bought the CD version of iWork 09, so they aren't linked with the App Store. When I open the apps after a new version is available, it gives me a prompt to update, but when I click it, it takes me to the App Store and then does nothing. Any help with this? I can't use iCloud compatibility with Mountain Lion with these dated versions.
