every time i try to log in, i get buffalo error. The game loads to title screen, but claims i must restart Battlenet and try again. Ive restarted Battlenet numerous times and it never helps, and I have checked to make sure Battlenet isnt undergoing servicing. Plus this has been going on for 4-5 days straight
Same here, nothing I tried has worked including running battle launcher as administrator.
I was having this problem too, but after doing a few things it worked, not sure if it was one thing or all but, I made sure I was signed out of Bnet everywhere else, restarted the apps, then ran bnet as an admin and opened D2 from there, maybe one of those could be of help
