Diablo® III

Hey guys after some serious searching here is what I found to work.

First of all. What is causing patch looping is have an EU client and trying to connect to US server. I live in canada and somehow got a EU client, this happened to many others to. If your in a patch loop, this is probably why.

This is ONLY for non enUS client & play NA server user.
If you are play in EU or ASIA server, please don't use this.



there is two plan, just choose one to do.



*************************************************************************************************************
PLAN 1
*************************************************************************************************************
1. please close Diablo3 first, and use Notepad open "agent.db" this file (*1)

Where is the "agent.db" file? (*2)
Win7 & Vista is in C:\ProgramData\Battle.net\Agent\agent.db
WinXP is in C:\Documents and Settings\All Users\Application Data\Battle.net\Agent\agent.db
Mac user can see this post (thanks NDT)

**NOT the Diablo3 game folder's agent.db !! (thanks Darkstaf and Eliarainne)


2. find ALL(there have three or more)
http://****.patch.battle.net:1119/patch and change to http://enUS.patch.battle.net:1119/patch

**** is your client version. (like below)
enGB
enSG

deDE
frFR
itIT
plPL
zhTW
koKR
esMX
ptBR


3. don't forget save file!! then close Notepad and restart Diablo3, it will update to 1.0.2.9749



IMPORTANT

1. backup the agent.db to other folder before you modify it. (thank Fight4Love)
