NTI never had a free version, they did have a shareware & demoware version of NTI2000. they may have given free updates to an older version, but i have used NTI since version 3, and had only been able to upgrade to 3.6 for free. never had a full working ver for free.
you can get a copy of the newest release to demo out which happens to be version 6.
the version your seeking is nticdmaker400.exe
