Uggghhh... Obviously not everyone's PCs decide to mess up all at once. Blizzard just needs to man up and admit the error is on their end and release a hotfix for this... Been a month since I ran into this problem and I still cant get it to work. Tried it all...
Deleted the Battle.net folder.
Made sure the Secondary logon was set to automatic.
Completely uninstalled and reinstalled the game several times.
Booted up with selective startup.
Started shortcut as administrator.
No firewalls up..
Even tried http://eu.battle.net/wow/en/forum/topic/5208782559?page=1
Nothing is working. Cant even log into Diablo 3 cause of the same downloader issue. Been killing time on GW2 til hopefully this issue gets worked out but its been over a month.
Seeing all these bluepost telling us to manually do this and that... Which we shouldnt have to in the first place. Game working 1 day fine.. logout and back in and its suddenly broken..
Would like to continue playing. But not gonna keep my sub going for something I cant even log into.
(Note to Blizzard. Fix your crap... We're not paying your company just to have you tell us to fix stuff ourselves.)
