Thanks for your reply. I will try to do what you have written, but I wander if that simple thing should take so much of my time and energy.
I tried to downlowd 3 differen virsions (up to 7.05 or 7.04) and I tried to run exporting on each of them. Now I downloaded new 7.10
So, I am trying very hard to make the VP working. I exported my project in Full HD. It ran great. But I need it in 4k. And it take so much troubles.
I have 125 4k files in my project. I don't have enough (apperently) space in GD to send you a link on Portable Projec ZIPed files. My ZIPed files were pain in the ass too.
WEll, I think I needed worry free soft to make 4k movie, thats all.
Respect,
