Hi Bud, This happened to someone in our TMG users group and it was caused by McAfee antivirus. You could try restoring a backup to another computer as a test to confirm it's specific to the computer the errors are reported on. In our TMG users case, they did not have to "use" the backup, but rather it was just to confirm the McAfee issue and once that was fixed on the problem computer, they were good to go with their last working TMG project. Others on this forum may have reported similar (missing file) issues due to the cloud backup program or Dropbox.

I've managed to avoid any serious problems in the over 15 years I've been using this great program. I went to fire up TMG this morning and got this. "Repair mode has been activated." I hit "OK" The TMG screen came up and it said it was loading, then I got this: the blue options screen which listed a bunch of options such as last, sample, select. etc. All choices are available except the "last" which is grayed out. I did not dare to hit any of the other choices not knowing what would happen so I just hit the "x" at the right top. Then I got this: The Master Genealogist (repair mode) message which stated: "An error happened when opening the data tables...File C:\PROGRAM FILES (X86)\THE MASTER GENEALOGIST V9\_ND.dbf not found." I hit OK and TMG is off my screen. What now? Bud Dorr
