Does anyone know where I can get a demo of Office 2010 Home an Student from, other than the MS website?

The reason been is I have the netbook here with MS Office 2007 Demo on it and the owner has decided to purchase a product key only to activate it, but has gone and bought a 2010 product key rather than 2007, then brought it to me because it doesn't work... Wonder why?

Anyway, I've tried to download the trial version from the MS Office site but everytime I click the "Try It" button, login, and fill out my details I get told they can't continue with my orders because there's "nothing in my basket" (thanks again MS for your wonderfullly helpful site ), so have resorted to getting hold of it elsewhere but everywhere just links to the office website.

Any help appreciated,
Thanks.
