A NULL interface pointer has been dereferenced.

[ZUZ3L]

Hi all

I am totally new at AE, but I have used Adobe's programs as long as I
remember. I had to try the Puppet Tool but ran into a problem.

I'd like to animate a guy I designed, dancing to some music. I can't
time it right unless I can move the Puppet Pins while the music plays.

It is possible to animate it in real time by holding CTRL (PC) down
and dragging. But with a audio layer with RAM preview turned on, I get
this error: "After Effects warning: A NULL interface pointer has been
dereferenced."

Can anyone help me with this one?? :(
