For about a week now, my log in information has been lost and forcing me to log in. On top of that after I random log out, I am unable to join every server after I launch the game. I am met with "Failed to log in: Invalid session (Try restarting your game and the launcher)". So, I do just that, and have to re-log in, and when I open the game to join a server I am again met with "Failed to log in: Invalid session (Try restarting your game and the launcher)"...

Yesterday I was able to re-log in and join after 4-5 restarts. Today I have done this 20+ times, and still unable to log in. 

I am running on Windows 8, but there hasn't been any launcher updates, that I can tell, that would change anything. When I went online to my.minecraft, It said something along the lines that region was correct with my account, so I had to answer some security questions and log in again on the my.minecraft site. I purchased in the United States, but since have moved to Australia. I have updated my passwords on minecraft and my email to ensure no one is signing in and messing up my log in verification. I have restarted my compute entirely and am still faced with this problem. I have tried older versions of minecraft and still cannot fix this issue. 

If there is any other details I can give to help, please let me know. 

Best,
