Launcher Closes almost instantly

As soon as I open the Launcher, it shuts down after, maybe, half a minute.
It doesn't matter if I press "Play" or not, or even do anything at all. It shuts down and creates some kind of bug report, "hs_err_pid" type.
I've included one of them in this report.
I have even removed everything to do with Minecraft, except for some save files, and re-installed it.
