Thank you for uploading the chinese client, but I have the same problem has some people already reported, the game quits by itself 30 seconds after connecting..
(ps: when it promps you to insert CD1, just say cancel and you can install)
Is there any fix? Do you think this is because Nostalrius detects the client as being modified?
The reason why I want to play in chinese is because I've been studying the language for a few years now and I feel like I could pick up some interesting vocabulary with wow..
EDIT1; Apparently I might have found the cause of the problem, I'll copy paste here, and edit once more when I've applied and tried out the fix (I have to reinstall everything first). In short it means that simply deleting speech2.mpq will fix the disconnects, but it will remove all english voices from the game. Then it explains how to get the chinese voice back I think but I don't understand, maybe delete speech.mpq and rename speech2.mpq into speech.mpq, I'm not sure, any help is appreciated.
如果用中文客户端的，要删除 DATA 文件夹里 speech2文件 这是NPC 中文语音文件，如果你要听中文语音 就先删除 speech 文件 把speech2文件 里的 2去掉就行
EDIT2: Ok all you have to do is to delete Speech.mpq and rename speech2.mpq into speech.mpq and voila, you have the working game in chinese with working sound and no disconnect. You can also /join china which seems pretty active, along with one of the various chinese speaking guild on either faction.
