battlefront II Closed Alpha invite.

I had been invited to the closed alpha test that had happened a couple weeks back. But I was out of town when that had happened and didn't get a chance to use the code and it is now expired. Was wondering if there was anything I could do about that? or if I would be able to get invited to the next one being as that one seems to be over. I have the code on hand if that is needed. Thanks in advance for answers.
