Trial / Tryout version 4.0 What serial # to use???

I just downloaded Photoshop Elements 4.0
tryout / trial version from the website, but when I try to activate, it goes through it's normal set up process and wants a serial number.
Tried typing tryout, etc. but that didn't work.
The adobe tryout website doesn't give any clues.

Thanks for any help!
