Is anyone else having an issue registering for SL? I just bought a MBP 13" (received on 8/20) and the form keeps saying the serial number is invalid. I checked the serial number for warranty status and it comes back fine. So, I started a chat with Apple (bad idea). The person just kept saying to click Notify Me. When I asked about the form, he had no reply other than to use Notify Me. What a waste of time that was. Any ideas?
