Game Downloads

When I try to register my game it doesn't unlock. What should I do?

Please double check that you are entering the license key and registration name (if applicable) EXACTLY as they appear in your registration email. Your name and code must be spelled, spaced, and capitalized exactly as they appear in the email — no matter how you regularly spell, space, or capitalize your name.

To avoid errors when entering your license key or registration name, the best thing to do is copy and paste them directly into their respective fields:

To copy: Use your mouse to select your registration name or license key, then press the Ctrl and C keys simultaneously.

To paste: Click in the box where the registration name or license key is to be entered, then press the Ctrl and V keys simultaneously.

Important! - Punctuation and hidden spaces are not permitted - make sure there are no leading or trailing spaces in either your registration name or license key.

Also note that many games have similar titles. A license key for one game will not work for other games. Please make sure that you are entering your license key into the correct game.

Shockwave license keys will only work on Shockwave games. If you have installed a different version of the same game (from a different Website), please delete it, then download and install the Shockwave version.

If you need further assistance registering your game, please send us a message using the contact us form. Under "Contact Shockwave regarding", be sure to select 'Questions about a game I bought' from the menu.
