Unlocking additional campaigns

1. Go to https://www.blizzard.com/
2. Log into your account.
3. Go to Account Settings and then Account Overview if you're not already there.
4. There should be a box at the top of the page that says Redeem a Code.
5. Enter your code from the DVD in that box.

It should then add Wings of Liberty to your account. If it doesn't, click the Support link (upper right of the page) and explain how you got the DVD, what you tried to do, and what you expected to happen.

If it is showing on your account on the website but not in the game, try shutting off the game and rebooting your computer. If it's still not working, back to the Support link on the Blizzard site.

Note: this won't work if someone has already used the DVD to install the game with that code. In that case, the DVD is useless to you. Because the right to play the game is not associated with the DVD but the installation code. If you're unsure if the code was ever used, that's why you contact Support. They can look up whether the code was used.
