try checking your junk mail folder, sometimes e-mails from companies are automatically sent there.
I got my demo by going to an unrelated site that recommended the use of codeweavers to use their program with linux.
here is how I did it:
1) I went to the following url:
http://www.acdlabs.com/download/chemsk.html
2) once on this page scroll down and click on the codeweavers crossover office link
3) download the trial version off the site
It sounds strange to me that you did not get an e-mail because I got my instructions to download crossover office the same day.
let me know if this works for you,
