I downloaded everything to no avail! ISO's fail to burn

[Jerry Schromm]

Hi everyone, I am not sure how this works or if I will ever get feedback. Anyway I just discovered FreeBSD yesterday. I read all about it and I am excited to intrigue myself with this new pc adventure. Sounds great and I will learn something about code at the same time. I feel it had a kind of old school feeling to it, at the same time cutting edge technology. I am a believer in it's viability over Microsofts Windows. They love to hide information from us not inform us.
 
The reason I am writing. I downloaded the 5.2.1 IS0's. I burned the boot disk successfully it seems. But I tried to burn the first big ISO file and it failed to burn. Some type of burn error following the track or something. Then I tried that other download that isn't the ISO but the regular files. That wouldn't do anything either. It burned but I can't instal it. That doesn't boot. Or install in anyway. 
 
I am wondering if FreeBSD is actually free or is this a way to get us to order the retail box lol. I don't want to feel that way. Yestersay I was so excited about this. I hope you can enlighten me some.
 
Thanks a lot,
