fredster: Sounds like something peculiar's going on. Is it possible you have 2 copies of the app, like maybe a trial copy from us, and a Mac App Store copy?

To uninstall the app, go to your Applications folder, drag OmniFocus to the trash, and then empty the trash.

Try uninstalling both and then re-downloading one (from us if you bought from us, from the App store if you bought it there).
