*READ FIRST*
Before anyone says to search, I have been searching for the past 3 days. I have tried multiple exe files, deleting the bin, deleting certain files. Force updating, reinstalling, restarting the computer, reinstalling Java, etc. My problem is that when I run minecraft and login before the Mojang screen comes up it shows a black screen for like a second or a 1/3 of a second then quits. Sometimes if I restart the computer the game loads up the first time but if I exit and open again it just closes like before, I have even tried a few un-official loaders to see if its anything like that. Its really starting to annoy me now and especially after I bought the game only a week ago.
