Airborne Daddy

Questions, I pre-ordered Sins earlier this week and was wondering how getting the Beta 3 worked? Will I get an email with a CD key in it? When I do get it How will I start to download it? Will I start downloading it from Stardock Central or will there be a link in the email?

If I pre-order today can I download Beta 3 when it comes out even if I didn't download Beta 1 or 2? This game looks awesome and I'm sad I didn't know it was coming out earlier . Iraq sucks!
