Not saving/crashing

Not saving my versions/crashing

What I expected to happen was...:
My minecraft launcher keeps signing me out. In this case. I loose everything, I loose optifine and any mods I download. I try to open a new version like 1.7.10 or 1.8 it keeps crashing. This is really annoying.

Steps to Reproduce:
1. I keep logging out then I log back in. none of my servers save, Same as my recourse packs same for my versions. I get logged out and in this case I loose everything. Its impossible to play minecraft
2. I try to do a new version of minecraft and it crashed "unstable version" before I had no issues but now I cant do anything but play 1.11
