I keep getting the error upon game startup that the game was unable to log me in through Battlenet (I use the Battlenet launcher). This has happened to me a number of times before, though I was able to "fix it" after multiple restarts of the client and logging in and out (even changing my password once).
Now however, my previous methods aren't working. I've also uninstalled and reinstalled the game, but I still keep getting this error.
Any advice on how I can start my game up successfully again?
