Winsock Packet Editor - Trouble

Hello,
recently i try to hack some MMOrpg game simmiliar like WoW, but its was china-story based game
i was trying to hack gold or xp using method packet sabotage, so winsock packet editor seems legit.
so, i try to record all packet (without filter first, mostly) analyzing them, and i focused for some hexadecimal packet when my char in-game sell something in pawnshop. Ok, transaction recorded. (i sell pearl cost 30 silver)
then i try to resend it with loop about 50 times per sec (without editing) and game got dc itself
ok that was my first mistake.
according to googling session, i simply had conclusion why i got dc
first, maybe the game have something like anti-cheat or game guard, so i cover wpe with hideztool and suspending some supicious download.bin in procces and i try to resend packet again... but i got DC again
second, i suspect maybe the packet traffic will going be decrypted before it reach server to prevent something like that happened. unfortunately hexadecimal is just something anew for me so i can't expect to going deeper with packet decrypting unless someone help me and tutor me ofcourse

i just noob with hacking thing
so a litlle bit an advice or more should will help

sorry for my english

Try packet filtering instead, I noticed in WoW that if I resent a packet it would kick me instantly, and I found out that was because the first four bytes of their packets are random opcodes that change every time, so sending the same one twice will never work. What I did though was filter certain parts of packets, like for example, if you're trying to sell the pearl you could record selling a pearl a few times then record selling a different item and see what byte changed. Hopefully you can find just one that changes, and that would probably be the item id. So if you add a filter at that byte offset you could make it so when you sell a pearl in game, instead it would sell something else.

That's what I did with wow, never found much except a server crash (would make everyone in an area get kicked for a minute and see "World server is down." error until the server restarted). That somehow got fixed within two weeks, I only used it two times and my friend used it about six times.

Not sure if the game you're playing has any anticheat shit, wow kinda does (warden) but you can have ce and wpe opened after launching wow and mess around all you want. Never got banned for that. But you probably can't resend packets for the same reason or a similar one.
