omg i fix it
!!
today i decide to crash my own server with that skin to see the real thing so i installed the skaraj skin and go into the server.
hm crash like i expect than i try to surf the net over and over for the solution
finaly in one little place i found something and read and i discover that i missed in my system folder the "TSKMSKINS.INT" because the texture file was there but the int wasnt so i took it from bonus pack manual install and go again on server and no more crash
!!!huray.
!
i now raise the ban for that guy who used the skin cause was no problem like pizzaman said
i also add the no3dcrash as mutator for security thanks admin.
one little file make me go crazy but make me more experienced day by day
SO CRASH SOLVED!
i will keep on eye next days to inform u if 100% solved
