Export of a video fails with Process finished unexpectedly
I have been using hit films express for about three months now and right now I am having a really big issue with exporting a one video, i.e. I can export all other that I have created so far, but not this. The only error that shows is Process finished unexpectedly.
Video lenght is 1:35 (I have been exporting longer), using preset Youtube 1080p (also same I have used in other videos). The only difference is that this one has more composite shots than others (but the transitions are not complex imho, few shakes, few zooms; in other that can export I have been using captions & stabilization).
My specs are Intel Core i7-6700hq 2.6GHz, 16GB RAM, GTX 6gb 970m.
Where I can find more error info? The one that shows is not really helpful.
