This has to be the worst-written application ever!!

I thought that after reflashing to a new, clean copy of Diablo and having TWO 8 GB SDHC Class 6 cards (one internal and one external) that I should be able to handle a 680 MB map of USA West. The download sits for hours and never seems to get more than about 20%. My internet connection is working just fine and other maps (less than 10 MB) seem to download fine. Is there a problem on their server or is this just a B-A-D program?
