Renaming Exsisting NPCs from Repack

Ok so. I have moved my starter npc to narootuh and replaced the items you get to my liking, everything went well.

I went into the config to "simply" change the name of it from "Welcome to KalParadise" to "Welcome to KalScrubs" (temporary name)

I see this

PHP Code:

---

(npcname 1525 "Welcome to KalParadise")
(npcname 1526 "Welcome to KalParadise")
(npcname 1527 "Welcome to KalParadise") 


---

I cange it to this

PHP Code:

---

(npcname 1525 "Welcome to KalScrubs")
(npcname 1526 "Welcome to KalScrubs")
(npcname 1527 "Welcome to KalScrubs") 


---

Save and close. Pack it up into a .pk through winrar with password, open it in Kal Online Advanced Pk Editor and save it as a .pk3 with password and add it to my client.

Run the client and instantly get antihack message and crash.

I don't understand what I am doing wrong. I am packing it up the exact same way I did when I edited the IP to let my team on the server and nothing bugged. Is there another place that the name is that it may be clashing with?

Thanks in advance, really appreciate it

PS: Here is the video I watched on how to make the .pk and .pk3 files. He's using the same repack I have. https://www.youtube.com/watch?v=WL-MeYd1xeA
