My minecraft will not launch. I have had trouble with my browser working lately, so I "refreshed" my computer. It wasn't supposed to mess with my personal files. But I had to reinstall java. I installed the latest version. I tried to launch my minecraft, but it won't launch. It will begin to load, but then come up with this error:
