The strangest thing. I reformatted a few days ago, and after I brought back my OpenGL renderer, it crashed on launch. Debugging it revealed that some basic OpenGL functions (like glEnable, glTexImage2D, glGetIntegerv) are not returning their addresses from the video driver, but plenty of others are! It worked fine before I reformatted. Any ideas (Yes, everything is updated)? How did it use to work before reformatting?
