Recently i bought minecraft for my p.c and when i tried to play it, it gave me an error message stating i needed to update my graphics card driver. My computer has an AMD Radeon R7 250 and i tried to update my driver using windows 7s automatic update scanning feature but minecraft still will not launch. Any help would be greatly appreciated.
