For the protection system to work, you need to insert the CD labeled "Disc Two" (or "Game CD") and then start the game.
Before doing so, you may want to shut down programs that are known to cause protection failure, such as Norton Antivirus and Daemon Tools.
Also, if you have more than one CD or DVD drive, the protection might require you to insert the CD in the other device.
If the protection check still fails, click the "information" button and mail the generated report to our support team:
