Hi, when attempting to open a specific .mpp file I receive this error message: "There was a problem opening this project last time, do you want to attempt a repair?" If I choose yes or no for the repair I still get the same result after, which is another message saying: "This action will cause a scheduling conflict. Task 266 of XXX with status upd...'has a task constraint or is linked to a task that cannot move, and as a result the constraint or the link cannot be set. You can, cancel or continue."Does anyone know how I can go about recovering this file?
