Minecraft Forums

My minecraft loader is not letting me load any new worlds, nor is it letting me create a new world. I have tried to delete minecraft entirely, re-downloading it and nothing works. It doesn't work in browser either... If I try to click on a world, it acts like my computer is frozen in the way it doesn't register at all, and when i mouse over the create a new world button it does not light up or anything. I've never really cared about the technical side of minecraft so I have no idea what to do/try.
