Got to admit I was having a hard time with it, didn't make any sense at all, but then I discovered that was down to the device I was testing it out on, on my desktop I couldn't get it to work at all, no contacts, just a mess, but then I noticed something odd and tried it out on my Surface Pro 3 and my Stream 7 and it all works OK.
Not saying it's finished software yet, but it does work to some degree and enough for me to actually set my wife up and show her how to work it (Long story) and she is happy with it.
I haven't got to the bottom of why it doesn't work on my desktop yet and that is the device I do all my testing/setting up on so it was really putting me off.
Good luck with it.
