Hi Golden, it's the weekend, I don't think Propellerheads staff are on the forum or strapped into their tech support pods.
I have the Windows Reason 304 demo. It's 65MB. I seem to recall it offered 20 minute timeout trials, which was great for getting the feel of the program and hurriedly making madcap experiments. Let's give it until the end of the day, if no-one else points you to a safe demo link online, I can send you a private message with a link to download it.
