I have been trying to get on D2 on pc for over a day now and have been getting nothing but Error Code: Buffalo. This happened after i uninstalled and reinstalled the game and i have tried everything from deleting the file that people suggest after doing %appdata% tto setting up a VPN which was also suggested and have had absolutely no luck. I even tried reinstalling the game for a second time to see if that fixed the problem. The current page for the error code in support is useless for me by the way as all it suggests for PC is that I am logged in from two PC's and ive tried changing my password on blizzard but nothing changed. Hopefully someone that has had this problem before will read this or Bungie will actually respond.
