Like other reviewers below me in recent weeks I am getting the same error message. I go to the purchases page and try to reinstall and get the same messaage over and over again. I was on the phone with apple for over an hour and a half with no resolution in sight. I tried everything they suggested to me and am waiting on them to now suggest giving me a refund. The new operating system has given me a host of other problems beyond taking my money for the app. Rename it El Marinero; it’s not ready yet to be called El Capitan.
