Newly installed HitFilm Express freezes up immediately upon opening
I've just install HitFilm. Upon opening it, a window opens that has a HITFILM EXPRESS menu along the top, but everything else below the menu is white, and I can't interact with the menu. The wait cursor appears, and never goes away. After several minutes I killed the process and tried again, but it happened when I tried again. I reboot, and it's still happening. I uninstalled and reinstalled the application, but it's the same thing.
I have an Alienware R4 with a GTX 1070 graphics card. Intel i7-7820HK CPU, 16GB of RAM. This happens every time I open the application. I seen errors in the event viewer. I disabled antivirus to see if it changed anything, but it doesn't help.
Any advice to further diagnose what's happening?
