"ok thanks sorry to keep u up. I will finish what I am doing on lite and
then upgrade to the new version. do I need to pay more money?"
If things are working for you, get your project done.
Then you will need to upgrade IRender Lite to either nXtRender ($45.00) or IRender nXt ($175.00)
(When you upgrade, you get all new releases for the new 12 months)
nXtRender has fewer features than IRender Lite, IRender nXt has many more features.
