Sorry for the title, but this is making me mad. So I hop onto minecraft so I can play multiplayer, and when I log in it says there is an update available, so I click yes without thinking. I realize this after I press yes, but that doesn't matter. Once the update is finished, it just goes to a black screen and nothing else. 20 minutes later still the same, so I delete the minecraft file and re-download the game off of Minecraft.net, try to play again, this time without doing the update, and it still gives me the blank screen. Any ideas? Minecraft was working fine yesterday.
