Beware that most are ripoffs.
The consensus is that you keep a backup copy of your database. If you don't this will happen.
One day my microsoft access database denied to open. I repeated the process, but no success. I use MS Access 16.0, I came to my friend who had previous version, but it didn't open again. Does someone know how to repair access file? Any solutions, because microsoft articles can't assist me.
