Not launching completely...

I love this app! Its really great and I love that it has a ton of options.
Except this new update doesnt not let me open the app. I tap to open the app and it just shows the opening screen (blue with the smiling pencil and some writing underneath) then shuts down, sending me back to my phones home screen.
I even get notifications from the app, asking me to draw and stuff but I am literally unable to.
This has never happened before the update. Please fix this soon because I seriously love this app and would love to continue using it.
