I just figured it out. The key is you need to think in terms of keeping the blades and the large washers separate. Here's what you do.
Thread the blade through the glass and use the white rubber gaskets against the glass and the stainless gaskets against the hardware. Then tighten the whole enchilada to the blender with the main nut (that goes on the bottom outside of the blender). Then once that's nice and tight tighten the flange that catches the blender teeth to the remaining portion of the protruding threads. Make sure you use the copper colored gasket first then the stainless washer then the stainless flange. Tighten that real good and you should be good to go.
To check if you've done it right spin the flange. If the blades spin independent of everything else you're good to blend away!

You can call Waring and they can send you a parts breakdown showing the order the parts need to be in. If you still have problems they can go over the assembly with you on the phone or direct you to a service center near you to help.

This is straight from the manufacturer:
Canada - Warranty Information
If your appliance is within the warranty period and you are experiencing difficulties please contact us 800-688-1989 or e-mail us at Customer Service. The Back to Basics Web site currently accepts and ships orders within the continental United States only.

Do you have any friends in the US that you could ship to? It would probably be prohibitively expensive compared to the cost of a new one.
