The best way is to get a new CD from EA. You can call EA Technical Support for more information. The number or email address for your country can be found in the installation guide, or on the EA Website of your country. EA will be able to replace your CDs, usually for a small fee. Note that you will need to send the broken one back to EA too, so don't throw it away! For the US and Canada website, click here

to find their website. Find the customer support section to find a phone number for contact. Note that ringing them is often quicker than e-mailing.
Be careful with your CDs! They're more vulnerable than you might think!
