"File was not created by FileMaker or is severely damaged and cannot be opened'
I have created a FileMaker database on my PC. I made a copy of my database and emailed it to my son. He just got a new MacBook and has FileMaker12Pro installed on it. He is unable to open the file I emailed to him although I am able to download the emailed file andopen it myself. He receives this message:
File xxx.fmp12 was not created by FileMaker or is severely damaged and cannot be opened
It looks like error 807. Can we get around this?
