Withings do not start

I am trying to get the Withings binding to work on OH 1.8. It did work in my previous version 1.7 (or was it 1.6?). I have put the Withings 1.8 binding in the addon folder, I have not change anything in the Withings settings in the config file (aint much to change anyway) and are waiting for the binding to write the start up message in the OSGI console. Nothing showes up (not from the Withing binding at least).

Have the set up procedure change since version 1.7?

I am runing OH on Win 7
