Access Database error... cannot open database.
Message says "The Microsoft Access Database Engine stopped the process because you and another user are attempting to change the same data at the same time"
I have searched for database lock file (*.dbl) but cannot find one. The backup file that we have available gives the same error. Can someone please help? Cannot repair because I cannot open the database.
Using Access 2007 (have tried to open a copy with Access 2016 but get the same message).
