Common Issues

Minecraft is still in beta so it is likely to be buggy. Here are some fixes for some common issues that people run into.

OpenGL Error
If you are getting the OpenGL error when you are starting the game then your drivers are probably not up to date. It's time to update them!!
If you are an AMD user download the latest drivers here.
If you use Nvidia, download the latest drivers here.
Intel GMA user need to go here, then select Graphics.

Hope this helps!
