I may have missed something but I think BS's problems are
1) No modem on the Desktop to use dial-up
2) No suitable cables for Direct Connection (which I believe needs cross-over cables?)
I am stumped for a quick fix - the only POSSIBLE idea I have is to get a friend to take away a copy of your doc on either a floppy or CDROM if you have one on the Desktop, and then to email it to you via the laptop for you to open and attach?
Wishing you luck!
PS You don't have an 'old' dial-up modem lurking inside or in a drawer, do you? If so, you could re-install it and set up one of BST's dial-ups.
