Data base cannot be read by records
I upgraded filemaker pro 12.4 to 12.5. I have Apple Mac 10.85. When I went to open data base it appears on screen. I open my records and when I enter client number it says "The file 'client data base' could not be found. I phoned support. We returned to FMpro version 12.4, did recovery of file and still no connection. Help!
