Problem on my game

I can no longer play on my game in the versions above the 1.10. When I try to log in in version 1.11, 1.11.2 and in Snapshot, its me mark that I can not access it. The error messages are:
Unable to save the download. et_ee.lang
Or:
 eu_es.lang
fa_ir.lang
 fi_fi.lang
And all a bunch of message like this.
When you go to youtube to fix it is problem, there was on a video a person who said that we had message, we had to directly re-press the Play button and redo its until its us Face entered the game. I have already tried this on Versions 1.10 when I could not log in and its walked. But this does not work anymore. So I registered on site to see if you could help me to fix my problem, because with friends, we had planned to play in 1.11.2 and do a series on server, but as I do not arrive Not connected to me in any version above the 1.10, and well its very gene me.
I wrote get message with Google translation, so if you do not understand all, this is normal.
Thanks for reading and trying to help me.
And also, I have the version of new Launcher in 2.0.847
But as there are not any on the forum down there.
