I keep getting an error 3 when I try to log on to Diablo. I was able to long fine earlier this morning. I can log on to my battle.net account and even attempted to change my password to force a reset. I followed all the steps outlined in the article but none of them resolved the issue.
I too am reciving the 3006 error. Was fine for a while then extreme lag. when i tried to log back boom...3006 error. Havent been able to log back in since.
Ok what I did to work around this problem was to go into the diablo 3 folder in my hard drive and start the game using the Diablo 3 EXE. file. Just double click to launch the game.
