I am having a strange problem: "This action cannot be performed because the required table is missing" pops up when logging in for a particular user. This only occurs on one Mac. If that user logs into the same account on another Mac, PC, or iOS, the problem is gone. FileMaker has been uninstalled and reinstalled on the machine with the same result. If another user logs in on the problem machine, they do not have the problem. So only one account has the problem and only when logged onto the one machine. Any ideas on how to solve this?
