Same random string, make sure you edit both "scripts\kabam\rotmg\messaging\impl\GameServerConn e ctionConcrete.as" and "scripts\kabam\rotmg\application\impl\ProductionSe t up.as:" to the new version.
This also might help @Kabelo666, did you make sure you changed both lines mentioned above in pcode, saved the edit, then saved the client?
