So, minecraft used to work like a charm for me, then something happened and now it doesn't, well, infdev works, and survival works, but single-player creative and multiplayer creative doesn't work, as well as indev. When i try any of those three, my cursor changes to the loading cursor, and it flashes one bit of text that says "switching applet", then the little screen goes black and doesn't do anything. Ive reinstalled java, cleared my cache and restarted my comp, even reinstalled firefox and tried it on internet explorer too. Nothing works and I am getting frustrated, please help!
