I have Minecraft installed but whenever I open it, it shows the login screen, so I login, and then when I click login, the window turns black. When I tried to play in in browser, the same thing happened except the window turned whit. Please help guys! I feel like I've tried EVERYTHING! Thanks! =)
Oh and if you want a better look at the problem, I've created this video that is a recording of my desktop and shows what happens when I try to run Minecraft.
