Just bought one and tried to download it (389mb) and it didn't work. So that was $20 and no pdf so far. I don't think these downloadable game stores have simplified the process enough or made it compatable with the normal programs that your average newbie user is going to have. I was looking the FAQ they have and their suggestions involve downloading new programs. Not something I'm comfortable with.
The first step is to explain in more detail what your problem was (just like you want clear instructions to get things done, we need clear instructions to diagnose the problem
Which site did you buy it from?
Define "didn't work"? The download didn't work? Or you couldn't open the file after downloading.
What program were they recommending?
Fair questions but moot at this point. I finally got it downloaded (DCC#35 is too big a download. Should be in several smaller downloads) and couldn't get it to work so they extremely kindly refunded my $20
But this is just text and images, and my system is windows vista and inetrnet explorer, common as dirt. I download a movie, no problem, I download music, no problem, but this pdf is a monster and turned out to be a waste of time.
Two downloads I was disconnected. The first one finished and disappeared. The last time I received error messages saying the file was corrupted. This needs to be as simple as downloading a movie and it isn't.
NOTE: Turns out DCC#35 as a pdf has some problems, especially with windows vista.
