Have to just add the features I tested past 14 hours straiight so now these features work ...

Yay! 

CMSbyCW now have solid architecture, not a hack

+ Software License Key and Domain Name Verification logic 
+ Working license + domain verification
+ Session-based access control (no exposed files)
+ Time-limited download access
+ Clean, human-readable flow (no weird parameters)
+ Extendable JSON logging

I set it up so that for the price of one, it can be used in 3 different active installations.  '

I also set download period initially, 2 hours.  But since it took me 14 hours to complete coding and testing and round round it goes, by the time I completed the process flow and coded and retested the coded, I ended up increasing the time frame from 2 hours to 24 hours.  (It was originally 15 minutes, and I increased it to 2 hours, to minimize tech support, and just put verbiage that says you have 2 hours to download. 

Why the limits?  To prevent downloads abuse.  Or piracy or Intellectual Property theft or Copyright Infringement.

I also put logging of download attempts.  

Because for software, this is usually logged.  

You purchase a software, and have to download and activate it. 

Because you can't request for a refund if you only purchased it, and then not downloaded it, nor activate it.  And then say it doesn't work.  It's like buying a burger, and then requesting a refund because you didn't eat the burger you purchased.  LOL! 

The software is already purhased and source code and tech logic flow divulged.  So, sorry, I will be putting out demos of this software so people can test drive it before they buy.    

Or they can build software too if they want.  :-)
