I'm retracting my previous negative review. The missing maps problem was fixed on Mon 18 Feb. 2013. This is a good module, now hopefully we will also get DA1 for the intro scenario for Blackmoor, and perhaps even the Judges Guild campaign setting. I always preferred Blackmoor to Greyhawk.
Thanks to RPGNow & WotC/TSR for fixing this issue so quickly!
