Ok so i was fooling aroung with minecraft and the millions of mods on the internet, and i dowloded a mod saying it has been updated for 1.4_01 but it had not acully been (haha april fools fml) so i got black screen. When i redownloaded minecraft it was not black screens (hurray) but it was the outated minecraft 1.3_01 instead. It is not giving me a option to update. IF ANYONE KNOWS WHAT TO DO PLEASE HELP ME OR I WILL DIE CAUSE I CANT PLAY ON OUR AWSOME SERVER!
