Game closes itself

Hi, I have been experiencing problems with the game since last Thursday. When the game starts, it closes inmediately with the intro. I have tried several options, such as:

  1. Re install 3 times. 2. Update everything. 3. Downgrade all updates. I am still not able to make it work. I don’t understand why this happened, I played for several weeks with no problems. Any suggestion? Thanks in advance!

I tried with a friend’s accout and it works that way. How can I fix it to make it work with mine?
