Move matinee sequence between projects?

I’ve got 2 projects an older one that runs on an old machine with 4.12.5 that features an object that falls over controlled by a matinee sequence.

Now Id like to move this over to a new project on a different machine that also uses 4.12.5 how do I do this?

Additionally matinee works fine on my old machine, but on my new one it crashes?
