also absinthe will usually throw an error at you if there is a passcode on the device and/or if the device's backup is encypted so check that as well.
ensure you are on 5.1.1 not 5.0,5.0.1 or 5.1.
redownload absinthe v 2.0.2 from the google docs official link and re-extract just to be safe. and also try different USB ports sometimes it buckles and may not sense the device from other ports and the button will be greyed out as well.
give those troubleshooting steps a go and report back.
