This just started last night when I went to launch Minecraft, my user name and password are deffinitely right, but once I go to login, it acts as if it will load Minecraft and launch it, but it opens a window for a split second and doesn't launch and I sit at my icon screen, I've tried to redownloading the launcher but that didn't seem to help, I went to try to launch it on a different computer which is newer than my computer much newer and it still doesn't launch, I can't play it at all, I would think this has to be a bug since it didn't even work on a much much newer computer, and I always have perfect connection to my internet. Please help me find a way to get my Minecraft to launch, it worked perfectly fine a few months ago when I was last on it, and now it won't launch. Thank you in advanced.
