camera crashing problem

hi i have a really weird problem that when i try and change camera or what a camera is following or even have more than one camera in the game it crashes. now this hasnt happened in other games ive done so i dont know wat it is.

if any one has any ideas why this might be happening it would be really helpfull.

ill post the blend if you want

thanks

its ok i found out why

Why was it? (It may help someone with the same problem)

There were two reasons.

  1. i had 2 cameras and i tried to make them follow different things but i realized that the actuator only affects the current camera so it crashed because it tried to follow 2 different things

  2. i had a camera parented to something and following something
