I had both downloaded PW jp & china Client. and i have installed China first but it wasn't a success. So i did uninstalled it and installed jp client but it wasn't a success either. I dont' know whats wrong with it, or is the client or the patch un updated? Although i did all the guidelines. But can't start the game, i think there was a problem on updating the patch or so whatever. Please help. Thanks

Try makin account on cubizone and then follow the other instructions on the other posts that few people have writed down and u will be able to play Mal/Chinees PW.
