Hello! My minecraft has got some errors recently.When i tried to launch minecraft it just came up with a bunch of errors(listed below) i've tried uninstalling java,reinstalling java everything with java. I've looking on the internet for about 2 weeks and none of the solutions has worked out. I installed the one package myself but then i couldn't log in. Please help! It has been like this for 3 weeks now and i have even bought a windows 8.1 cd to restore the computer but i can't even install windows 8.1, after it says Prepairing 99% it shuts down and nothing happens.
