Just dont use the installer...extract the files from the zip to ur l2 folder..change the name of l2.exe and l2.ini to sth else and rename lineage2.exe and lineage2.ini ti l2.exe and l2.ini..then open ig walker normaly:)
Try ig....I dont know if walker will make it...ill try l2 net
maybe u should find an other pack...and interlude is better i think because u can have new gm shops and buffers..try oneo or titan energy both very good packets;)
