Thanks for the suggestions. After a heroic team effort, I have finally had to admit defeat. Yes, I am positive I was trying to download the right file. And, actually, it downloaded just fine. I just got the windows 32 bit error every time I tried to open/install it. We tried cleaning registries and disabling anti-virus software, but no dice. Guess I'll have to call in the pros for converting my files to epubs. Hmph.
