I am doing it with offline utility. I couldn't find a way to save my progress. Will again try to do from scratch.
Assholes have two utility listed on the site if you download without login you will get 1.0.5 ver which doesn't contain itr3

confusing people even more.
After login you can download 1.0.7 ver which works normal, even in the final preview pdf everything works. At validation it keeps showing that error which doesn't even exist in preview pdf.
In the end that utility also strated to freeze. So much time wasted.
