The problem was the file Mylog.db3.bak not know what happened internally at RB for this to have happened. Now I copied the file Mylog.db3 and changed the name to Mylog.db3.bak and you're OK, but still made me lose flights yesterday and today.
Best Regards
P.S.-But I came back to turn off and on the software and returned to lose the data, ie the Mylog.db3.bak is not updated with new data and when it reconnects the software, it erases the data and replaces Mylog.db3 by Mylog.db3.bak data.
