Ok, using SWSRO Files...
Before, I don't know what i did but like i was using my server with ZSZC's Files and worked..
Why i used ZSZC's client ? Because of the sro_client and silkroad.exe those are better since silkroad.exe doesn't need compatibility so it runs perfectly... and the sro_client because it had the "Hide Players/Objects ( v key )" Well i think its the sro_client but it also because when i close client (MHTC) it says sro_client stop responding and with zszc it doesnt happen.
I cleaned my pc etc i re-setup the files etc and when i use zszc client now it gives me C8 and with MHTC it doesnt happen the C8 -.- so idk the problem..
So...
Any silkroad.exe (No need compatibility) and sro_client (that have hide players/mobs) that works with the mhtc files ? :P
