While I'm here I'll give you a couple of things I found out about the program, as it has a few quirks:

First, make sure you disconnect from internet connection before you press start, other wise instead of starting up a connection it shuts it down (and then re-starts it when you press stop)

When you press start it will ask you to select a connection. If you accidentally select nothing, or the wrong one, activate it by pressing your status bar before you press stop. Then you'll find it is shut down by the program. Then starting it again will ask you to select again. Otherwise if you cancel the connection and then press stop, when you press start again it won't ask you to select a connection.

Also i found you can double tap the 'stop' button to restart the connection, which I find i need to do from time to time..
