I bought it from Sim-Central, I've even gotten an email, then I went to my Auran Profile to look for the downloadable ticket and its not there.
Since you used PayPal, there may be a "glitch", in that, there is an ongoing issue for SOME users of PayPal when purchasing from Sim-Central, where everything appears to have been finalised, when infact, PayPal has not actually transferred funds to N3V yet, but sent you a email saying "transaction complete".
--While it is true, your "transaction" with PayPal has been completed, PayPal may not have completed THEIR transaction with N3V.
Incase that is not your situation, check again on Planet Auran, under: click Download Tickets (left menu), then on page "Planet Auran: Tickets", scroll to the very bottom, where your expired tickets are...You have nothing saying "activate now"?
I'm not far from Philly, and I use PayPal at Sim-Central, I usually get things within minutes...so I doubt it is an "internet-communication" issue.
