I have my src 1453.
I downloaded this
https://www.kodevelopers.com/unpack-exe-paylasimlari/12-1453-knightonlineexe-unpack-amp-bypass.html
and changed from
"#define __VERSION 1453"
to
"#define __VERSION 1483"
but the game stuck after login (autoregister enabled, but i don't see any insert in TB_USER table, so that means this is not working, so what can be the problem? please help me)
