bobo remember to join us in 狼狂索斯 PVP.
also, you need to install chinese fonts else u cannot read the realm list.
unzip the fonts folder into your wow program folder.

EDITED, don't wanna let ppl bring me down to their immature level and beat me with their experience.

Go into 查询服务 on the left bar then you will see it.

ah, my bad. click this on the left side.

well, you might as well learn some basic mandarin too ahah.


查询服务
查询 = check, checking
服务 = service

it is the 3rd button from the top, on the side hand side bar.
and then you click this button:


储值历程查询
储值 = reload, top up
历程 = history
查询 = check, checking

2nd row from the top, 1st button from the left.
then click this:

剩余时间查询
剩余 = remaining
时间 = time
查询 = check, checking

button on the left.
also, i think using latency fixes tends to cause more disconnects.

39hrs 40mins

39 hours
40 minutes

小時 = hour
分 = minute

Yo, hey bobo, long time no see. Stopped with Minecraft already? For Taiwan version, the only way to check game time is via Taiwanese client.

Have you modified the realmlist as stated? It should not launch the launcher if the realmlist is as shown.

1. Restore version 4.3.2 WoW.exe and Battle.net.dll
2. Run repair.exe. This will repair version 4.3.2
3. Run launcher.exe. Make sure there are no additional patches.
4. Follow the steps to downgrade to 4.3.0
