Here's another link that may help.

They have some manuals (not sure if the one you want is there, couldn't see digi-troll 2) however, it is the cannon site and you can try sending them an e-mail. They may charge you for a hard copy of the manual. You never know, they may be able to send you a pdf copy or some other format of the manual via e-mail. I hope you find what you're looking for. I've been in your shoes before and know how frustrating it can be. Good luck!
