Bad video card drivers!      
      -----------------------      

Minecraft was unable to start because it failed to find an accelerated OpenGL mode.
This can usually be fixed by updating the video card drivers.

Every time I try to play I get this.. I don't have any mods or texture packs on minecraft.
I just downloaded it today to give it another try and, it still didn't work.
