Got it working used the instructions from adrianapep91
But initially it still failed so I :
1 reinstalled windows 8 completely
2 deleted the app from the phone
3 deleted my nike account
4 redid my nike account with explorer no antivirus
5 downloaded nike connect and installed on PC
6 plugged in band and reset it to factory conditions
7 reinstalled the app on the phone
8 logged in to the band with my new account and set it up
9 turned on bluetooth on the phone and ignored it trying to discover
10 opened the app on the phone and logged in
11 disconnected the band from PC
12 waved band about to make it add a few steps
13 the app detected the band
14 checked bluetooth settings on the phone and it has joined to the band
This method works I'm not sure if chrome or Firefox fudge the process up so use explorer
I just daren't turn off my phone now ;)
