If you use my 'classic' instructions above, BitTorrent does a checksum on the downloads automatically, and the files have always worked the first time for me. And the download is 1 file (not 1 file broken into 6 parts to download). I know I'm preaching to the choir, but I don't get why you guys don't recommend the normal way that every other person usually installs this. Everybody on the SAS forums does it this way. (Ok, I'll shut up now).
