I think I am SOL. Back when Beta Phase 1 started - I didn't realize the email had been sent to my Junk folder. I happened upon it at work when day and was like "OH CRAP" - and by the time I made it home, my junk folder had emptied itself (it has a two week auto delete on it) and I lost my registration code.

I never found a way to get it back so I'm fairly sure I'm stuck. I hope it does not exclude me from any early playing post P4 though.
