The program shuts off, unable to create or open scenes

Today I bought the student licensed Harmony Essentials, but I can’t create or open files, the program just shuts itself off. I don’t even get an error message.

I tried uninstalling and reinstalling the program, graphic drivers, I also tried changing the directory of the program and the files to no avail. Also turning the computer on and off of course.

I need to do school assignments and I do prefer this software over Photoshop please help.
