EA have a released a game de-authorisation toolkit as part of their renewed effort to maximise single PC game releases being used on multiple machines.

Certain EA PC games with SecuROM digital rights management technology allow users to concurrently "authorize" up to five computers at the same time to play the games. Users can then play the game on any authorized computer they choose. If your EA PC game was released after May 2008 and has a machine authorization limit, you can now manage your computer authorizations using EA De-Authorization Tools!
