I received a key for a different region - can I still use it?
You may still be able to use the key and play the game or use the software by using a VPN (program that let’s you change your IP to a different location). Make sure you use a country on your VPN client that is not restricted for your purchased product.
The information about regional restrictions can be found on the product page, for example: “Region: Global”.
Click on the “Check country restrictions” link next to it to see a detailed list - if you can’t find your country there, that means the product is restricted in your country and you may need to use VPN or other methods to activate it.
