You should be able to download it & run it for 14days as a demo before needing to buy a license for it.
It was version 0.8.0.3 you tried to download & not the Beta wasn't it?
The Beta is only available to those who already have a BTB Pro license...
Just tried myself a few moments ago & the Demo download link worked fine, I just had to log on to the site which is free to do
Goodluck & welcome to track building!
Thank you for your reply!!
That's strange. I did login in the BTB website and only clicked "full download v0.8.0.3," but I still got the "Error 404: NOT FOUND!" webpage. These are the screenshots: The Bobs Track Builder Pro Download webpage http://ppt.cc/JkDt
