My Morrowind GOTY DVD disk was reading fine yesterday on my MSI GT70 laptop. Then I took it out to watch a bluray movie and when I put the disk back in, the laptop doesn't read it at all. I've had this problem before and I've cleaned it in the past by wiping the disk on my shirt or using toilet paper. And so I wiped it several times and inserted it into the laptop and the computer just won't read the disk. So now I cannot play Morrowind. What gives? What should I do?
