Studio 360 Still Not Loading - Just Hangs

I am at my wit's end. I have gone back and forth with Articulate in emails and done everything they have suggested, but I cannot get Studio 360 to install properly. It just continues to look like it's loading at the very end. I've even left it overnight, and nothing. I have uninstalled, cleaned, and reinstalled it so many times my head hurts. I created a new admin account and tried to do the same thing as suggested, with the same results. Also, since Studio isn't loading properly, I get an error every time I open PowerPoint because the Studio plugin is missing. I can't be the only one having issues. Can anyone help me solve this? I've spend and lost SO much time on this, I am honestly ready to try another program to create my content. I added a picture of the screen.
