The error above appears when you generate a PGP key in SalesManager and you already have previously generated a PGP key in that same computer.
To resolve the issue you need to delete the existing PGP key in that computer by deleting folder named ' 3dPGP' that can be found inside the Application data folder, please see procedure below on how to delete the 3dPGP folder:
- Close SalesManager
- Click Start menu
- Open Run or command prompt
- Type in %appdata%
- Press enter
- The Application data folder will open
- You should find the folder 3dPGP and you can now delete it
After deleting the 3dPGP folder you can now regenerate the new PGP code and re-setup payment methods accepted in your shop.
