a new issue.. with adding stuff to pcks

i added some stuff to my pcks.. and the client works i can login but right when it gets 100% loaded it crashes client.. which i did add alot to all my pcks. so cant figure out right off top of my head which one.. also when i put the skill effects off of this forums.. i could see the skills fine.. but some of my weapon effects was gone.

Check interfaces.pck. replace with old 1 and check if it work.

ok i replaced em 1 by 1.. and its the surfaces.pck.... which now the problem is to fix it to work
