It Always says it is something with the imagery in the computer or something but i dont think i have a old computer to be telling me stuff like that..for example when i try to play minecraft classic and error message code pops up saying something is wrong with something to do with the imagery or the pixels and i am getting frustrated..and this has happen with other games also
