OK so i was trying to download the 1.8 pre release onto my comp so when i tried to run it said it was doing some thing with files or somthing and then it just stopped on "done loading" and there is a little bit (about 1 cm) of space left and i cant get minecraft to run can someone help? if i try to download it again i get the same exact "done loading screen it might have been a big mistake but i deleted everything that had to do with minecraft on my computer (dont laugh im a computer noob) thanks for any help you've got
