I have another possible fix! For me what I did was: I went into settings and selected always use beta builds. Then for the Lols I selected increase PermGen size. I don't know what it did but it fixed it for me and that's all that matters. :)
Thanks for that. Call me what you willI but i said that because people are reporting far more problems that this. And It seems to me like they all have something to do with the new launcher build. Kill me for voicing my opinion.
