This is your problem, essentially. Intel GPUs are notoriously unreliable when trying to execute Shader code; Given that our shaders rely on features found in OpenGL 3/4 compliant hardware, and yours is only rated for OpenGL 2.1, you will need to disable shaders on your system. In the Launcher's troubleshooting section, there should be an option to disable Shaders altogether, if you can't find it, you nseed to pass the -no_glsl parameter to the executable.
