Register AppleCare error step 2

Hi,

I bought a new Macbook Air two days ago and started registering for the apple care protection plan.

I could enter the registration number and the hardware product serial number.

But when it came to load step 2 (Terms and Conditions), "We're sorry, an error has occurred while processing the request. Please try again." occured.

Does anybody have the same problem? What can I do now?

Thanks for your answers in advance!
