Your game menu will have 2 choices, Remove Game Authorization or Remove Other Authorizations. When removing your codes you should always remove your add-on authorizations first, then your game authorization last.

To Remove Other Authorizations click the menu choice, select the authorization from the list and click the remove button. Enter or verify your product code and click OK. Repeat this step for each add-on product that you have installed and need to remove.

To Remove Game Authorization click the menu choice and enter or verify your product code and click OK.
