Mirillis Action! Crash

[Kanooka]

So basically I can open mirillis action once a day. After that it crashes my whole computer (freezes it so I can't do anything) so I have to shut it off. I am using the Trial Version. I saw this format thingy, so I guess I'll use it (i'm new, first post )
OS: Windows 8
Video Card: ATI 7750
Memory: 8GB
Monitor Resolution: 1920x1080
Video Editor: LightWorks, but that doesn't really matter
Game Problem: Minecraft, but it works fine when it open
Video Type: AVI
Thanks for your help and if you need more please tell me
