help extracting recvpackets for private server

[aapikz]

i followed exactlty http://www.openkore.com/index.php/Connectivity_Guide
i sucessfully got the ip,port adress, version..and i logged in perefectly..
my character slots.stats.job ,level and everyting works fine ..

but it seems it wont detect players,monster,npcs
i assume the problem in on recvpackets.. which i had a big trouble on extracting it

i already tried jvc tools extractor and openkore extractor
but it says

Packet length extraction started...
==================[ ERROR ]==================
Sorry I cant find the offset of the packet length function.
The executable file might be compressed/protected.
==========================================
is theres something i did wrong? i followed the connectivity guide correctly and i keep getting error

would you mind if you help me on extracting this private server

Hello, I used the Packet Extractor v3 and it worked fine. The file isn't protected.
I made a pastebin of the gained information.
