Short comment, when setting up my own server with this guide and the files provided, I ran into problems due to the Nation Codes in the files: WorldInfo.ini, WorldSystem.ini, BillingSystem.ini, AccountSystem.ini and LoginSystem.ini. You have to change them from TH to RU.
Also if you set the zone to be RU nation code, you have to disable Fireguard on FGRS.ini.
And if the zone gives you errors when trying to start it, modify rfacc.ini in the rf_bin folder of the zone, since it apparently the dbstr line has some faulty code.
