I have sold a number of Nike+ Fuelbands recently - they're great devices and not yet available in Australia. A great review can be found here.
A couple of people I have sold them to have had a problem that after a period of use when connecting the device to a computer running the Nike+ Connect software the software will start and hang on "Connecting to Nikeplus.com".
Reseting the device manually from the band does not resolve the problem. The fix is to disconnect the computer from the internet. Then reconnect the band and you will be able to access the Nike Connect software and reset the band from with-in the software which appears to resolve the problem. You can then reconnect to the internet and follow the setup wizard for the band and everything should be back to normal.
Hope this helps. I couldn't find this solution searching the internet...
