My FoxPro Began to Be Have Strangely.

I didn't use the newest version, because I was used to it and thought it was more convenient in my work, but recently it began to give me a lot of mistakes during my work, which forced me to update the software. With the update, the errors did not appear again, but the important file was corrupted. The DBF file tried to open the plugin from the TotalCommander BaseView. Opens with hieroglyphs: Then I did not understand DBF and came here. What to do with it now?
