Minecraft New Player Help!?

From my own personal experience with this annoyance i know of no real remedy for it except keep troubleshooting different things. Try going into your start menu and find the "search" button and type in %appdata% and ".minecraft" should be one of the very first things to come up, if not than search for it. Once your in there just completely delete a file named "bin" and than restart your minecraft and it SHOULD work. If not than just keep playing and it should sort itself out when there's an update
