I has been stuck 2day for cant log in the asian server after patch... while i log in, its ask me update for the latest patch but i already done...

I am using a windows 7 laptop.

here are those step

1. show all hidden folder

2. go to
C:\Program Files\Diablo III
.agent.db
just change "patch_url" : "http://enGB.patch.battle.net:1119/patch", (in my case)
from "enUS" to "koKR" so u can get patch 1.02a from korea patch server

3. go to
C:\ProgramData\Battle.net\Client
.agent.db
just change "patch_url" : "http://enGB.patch.battle.net:1119/patch", (in my case)
from "enUS" to "koKR" so u can get patch 1.02a from korea patch server

4. go to
C:\ProgramData\Battle.net\Agent
agent.db
just change "patch_url" : "http://enGB.patch.battle.net:1119/patch", (in my case)
from "enUS" to "koKR" so u can get patch 1.02a from korea patch server

Launch D3 and it will download a 15MB patch. After that you can play.
Hope it helps, it works for me

Note:
1.Using notepad to open the file...
2.after open, use crtl + f to find "http" this way will help u more easier to find http://enUS.patch.battle.net:1119/patch
3. Remember Agent folder got three need to change to koKR
