Had to move all my applications from external hard drive to MacBook today and am not able to get any iWork programs to work. I'm running 10.6.8 on a machine that was running iWork apps just fine yesterday. I also ran the installer file again and made sure to download updates. The error message I'm getting says Pages is not compatible with my operating system. I don't see how that can be, since it was before. I checked permissions on the file and I have full access. Anyone able to offer a suggestion? Thanks. *Edit: I should add that I had to do a re-install of my OS today as well, but I am sure I have downloaded all software updates.
