I am using magic launcher and I have read other topics about this and I don't like it when minecraft crashes on me for some odd/dumb reason when I installed them correctly so I was really mad when I got this error. Here the thing and please remember I use MAGIC LAUNCHER!Plus I got no internet problems.
