Don't you know your client version?

Try to use guide:  L2.exe - ( right click - options ) - object. In patch line to l2.exe add with backspace -L2ProtocolVersion.

Author: Mifesto ( from mmo-develop )

L2ClientDat - Fafurion\Classic - You can edit .dat, *.ini Lineage 2 packages.

Updated structures to 166 ( l2.ru ) and 196 ( lineage2.com ) protocols.

P.S. It is advisable to open from under the JDK.
