First, I'm not sure if there was a complimentary PDF involved with the purchase. I am pointing people to Customer Service to see if there might be, since people who had purchased at Origins, bought it before the PDF was available.
Second, GenCon is in SIX days, and everyone may be a bit busy loading up all their stuff to ship across the country to make sure everything is there. As I've pointed out before CGL produces Shadowrun, BattleTech, D&D Dragonfire, and a few more games, while only having a total staff of around 35. Give them time.
