Windows Error! (need help)

Hello everybody! I dont know why, but when i cast a spell with the GOD character, it works fine, but when i use it with a normal one the tibia client crashes.

It says this

creatures.cpp 1564: assertion failed (spell=181)(delay=2000), reason:
spell < SPELL_BEYONDLAST

Anyone knows what could cause that? The funny thing is that when i relog into that character, it did use the spell perfectly fine.. :/

EDIT: i've found out that its when i use more than spellid=180.. how can i use spellid furthen from 180? thanks
