Missing the CD? Dont Worry

For Blizzard Games
  1. Once the account has been created, you will need to verify the email address and register any games before you will be able to download the required files. While on the Battle.net Account Management page, look for the Account Details section. Beside your email address, you'll see a Verify this Account button. The verification email will be sent to your registered email address.
  2. When you've completed this step, you'll be able to download Blizzard games online. Click the Add a Game button. If you purchased a Blizzard game previously, you may enter the CD-Key in the field labeled Activate a Game Key. Once a game has been registered, you will be able to download the game using the PC or Mac download icons on the right side of the matching games section
You can download the Trial Program for free, and activate it to full license with the CD Keys you have.
