PokerTracker

I moved my Mac DB to PC and i did not convert the .cfg files but I still have an issue with my name not showing up in the "View Stats" section. It says to choose player but I cannot see my name. I tried to instal DB various times but it wont show.

That's nothing to do with .cfg files and they shouldn't be transferred between different machines. Did you receive confirmation that the restore completed successfully? Do you see your restored database under 'Database -> Database Management'? Presuming it is there you should make sure it is set as the default/active database in PokerTracker 4 so you can see that data:
