Since patch 1.2 I can not log into the game. Every time that I do attempt to log in, I am presented with a Code 7 error and the game terminates. I’ve attempted to restart the Battle.net launcher, restart my PC, and run the repair tool in the Battle.net launcher. I am hesitant to reinstall the game as it is a time consuming process, but will do so if deemed necessary.
Re-installing the game has not resolved this issue either. At this point, I am 100% unable to play the game. 
Checked whether or not it may have been the WiFe that was causing this. I’m now directly plugged into the router (250+ Mb/s speed) and still a Code 7 error.
