Hello. Please note that since v1.5 you should use your serial number(!) in order to exchange on Steam key, but NOT the product code or the activation key! Your serial number is located in your purchase confirmation email that you received after the payment.

If you have not found the message with the serial number in your mailbox, please provide us with following information:

- Your full name, country and city;
- Version of the game, you've purchased;
- Your order ID;
- Your method of payment;
- Time and date of the purchase;
- E-mail that you've entered when paid.

Please send all this information to our e-mail: [e-mail]
