Quake3World

I keep getting kicked any time i make a game instantly online or off...
sometimes it shows the error
"wrong client cgame(some numbers)ARXINAL"

anyone know how to fix this?

Do you have version 1.32 of both Q3 and CPMA? Full CPMA install with all 37 maps? Look in your "\Quake III Arena\cpma" folder and make sure only the pk3's z-cpma-pak100.pk3 and z-cpma-pak132.pk3 are there. If everything fails, delete CPMA and reinstall it.
