Stuck with ERROR...

[Kaido]

I currently inside Yamataikoku. Yeah, stuck. Its not like I stuck in there because I don't know which way to go, but this is really weird for me. Whenever I leave the town, I got this Error (ERR_00000) and slightly disconnected from the server. I downloaded a new onigiri.exe and updated it, but still. Tried about 10 times already, but nothing happen. It keeps disconnecting. I create a new character. Smoothly play, no Error, easy kill. But my first character?!! Damm, I tried so hard to levelling by my own. Too sad I can no longer use my first character. This is just me I think. My internet connection seems to be in green light. My friends here beside me, plays onigiri too using the same modem wifi. This happen after the maintenace break. Even I cannot repair my weapon. Someone help?
