How do I update to the new version of forge (10.13.1.1225) from 10.13.0.1208

Hello, I have a custom Technic mod pack and when I add the new modpack.jar it does not launch. Where would I find the natives folder or whatever I need in order to get it to start? Please let me know.

 

Thanks,

What do you mean with "it does not launch"?

It crashes?
