Hello I made a short video about my problem because its hard to explain. I want to mention that Hitfilm 4 Express worked perfect on my pc but i had to reinstall windows 10 it doesnt work anymore. For lazy people: when i am in the project screen or export screen it dont show me the project screen or edit screen, it shows me the edit screen.
my laptop: i5-4210U CPU 1.70 GHz 2.40GHz
nvidia geforce 820m
