    I am stuck with my L2 server. I am web developer and know almost nothing about L2j. I have awekening latest version server release which runs on protocol. 531. I have a L2 client version GoD which runs on protocol 415. I've tried to change it but, after logging into the game get prompted with error message: failed to purchase item, error code 0. Trying to create champion results in disconnect. Gameserver message: WARN Unknown packet on state: CONNECTED, id: d0 from 127.0.0.1. Question: What can I do with my l2 client in order for it to work? Currently I have edited windows host file with my local IP and copied and renamed l2.bin to l2.exe, I also applied wildcard for system which removed error code on Game Guard.
