For some reason, Blockland crashes before I get to the main screen. The last thing to be displayed on the console is: "Accelerated OpenGL Display Device Detected." It just did this out of the blue one day. No computer program, settings, drivers change/update or blockland addons downloaded between the time it last worked, and the time it stopped working. Reinstalled removing all old addons, still didn't work. Installed on my laptop, and my laptop gave me the same error.
The only thing that I did that had anything to do with OpenGL between the time of it working and not was test Runescape running in OpenGL mode for a friend.
