Can't run project after updated ionic v 2.0.0

I’ve recently discovered that there was an update to Ionic and i therefore downloaded it from version 1.7.1 -> 2.0.0. But since it got downloaded i haven’t been able to either emulate or run the project on my phone. It works fine on browser with the current version and can both run on emulator and phone with the old 1.7.1. How do i fix this problem?

It looks like this with emulate:

On phone it just won’t load and all white screen.

UPDATE: Current versions:
