Charmaine,
It is actually the Michael Jackson Portrait site that is responsible for getting your purchase to you. That site can verify that your payment has cleared, and send you a new download code, or even send it to you directly if that is their policy. E-Junkie is a service provider only. (A very good one, incidentally.) I've been with EJ over two years, and glitches like this are very rare. So use the contact information on the Michael Jackson Portrait site to explain your problem and get your download.
Best,
Coach
