anyone know why it wont login

I cannot do a update that battle net told me to do and I cannot log in because the update cannot up date and keeps on saying this

BLZBNTAGT00000840 Something went wrong with a file. We’re not sure what caused it, so please try again or click the code below for more information. Sorry about that! And my wife and not log in because her authenticator keeps on asking from her old number that she do not have any more

My update auto installed. But i had to restart battlenet i think twice.
But after the new COD MW update 1.13. I keeping having the game crash mid play. During a multiplayer match. Hopefully they fix this issue its killing my vibes.
