How to reinstall Pages?
I recently had to get a new hard drive for my computer. Before doing so I could only manually back up my information on to an external hard drive with the help of the Genius Bar in an Apple Store. I copied my iWorks folder on to my external hard drive and the dragged it back on to the new one. But this doesn't seem to have worked because I can no longer operate Pages, Numbers or Keynote. I also cannot find my iWorks installation disk so I was wondering if anyone knew how to reinstall iWorks without the disk?
