Your Region is determined by your Viewing Card, not where the box came from. However ifd the Viewing card was bought from came from Scotland then you need to follow the advice in the previous answer.
However, if the Viewing Card gave the correct Region on a previous box, try this: Remove the Viewing Card. Unplug the box. Wait about 20 seconds. Plug the box back in. Insert the Viewing Card when prompted.
