I was playing with settings and changed the display method to open GL. A window popped up asking me to restart the program. I did that, but now the program wouldn’t start. When I click the icon, it starts the splash screen but then nothing happens. How do I undo that last change? is there a setting…

the reboot didn’t work. so I had to go to the registry and manually delete the keys. it started working again. Thanks for your response.
