Help Skillname protocol 235

[SadStatue]

Good afternoon lads !
I'm wondering if someone solved this or knows what's wrong.
Whenever I save skillgrp with an addition, or even a single digit change, using l2clientdat, the client crashes.
If i remove that addition and save again it starts normally.
Here's  the crash :

Protocol: C_LOGIN(39, 0) <= S_VERSION_CHECK(26, 1) <= C_VERSION(275, 2)

History: FL2MSItemNameDataManager::OverwriteSkillData <+ skill ID [32664:1:0] <- FL2MSItemNameDataManager::Serialize <- FL2GameData::LoadBinScriptAtOnce <+ Bin: 445204 Text: 2038171 Time: 2020.1.16 16:29:10 SHA1:66D9FBB8FE23274B6F6364B8D0EF6DC2AB98293D <- FL2GameData::MSItemNameDataLoad <- FL2GameData::LoadScript <- FL2GameData::LoadAlternateScript <- UGameEngine::LoadAlternateGameData <- UGameEngine::OnChangeServerType <- VersionCheckPacket <- ClientCmd <+ size:23, disassem:25 <- UNetworkHandler::Tick <+ Protocol Name=S_VERSION_CHECK <- UGameEngine::Tick <- UpdateWorld <- CMainLoop::UpdateTheWorld <- MainLoop
