Title: Borderlands 2 Need help creating a lan

Hello people, I've tried creating a lan for borderlands 2 with hamachi. My friend and I are connected on the same hamachi network and when we try connect to each other on borderlands 2 we don't see each other. Can anyone help me please?
I am using windows 8.1 and my friend is using windows 7 maybe that's a problem?
I'll include some screens of things that might be useful.
