GLW_StartOpenGL() – could not load OpenGL subsystem
This error: “GLW_StartOpenGL() – could not load OpenGL subsystem” is caused by the game not being able to detect your Open GL drivers for your graphics card.
If you have this “GLW_StartOpenGL() – could not load OpenGL subsystem” error appearing in your game’s startup window, you have to update or reinstall your graphic card’s drivers.
Just go to your graphic card’s manufacturer website, download and install the latest driver, which fit with your card. If this doesn’t work, just go uninstall the actual driver and try reinstall it.
