@elsourcex yeah seems they changed the url name from 'Bo' to 'urlLogin' , finally some sanity!

in any case, seems microsoft changed more than just the name of the url,

since i don't need this myself now, i can't be arsed to update it for free, but if you're interested, i can probably update it for $50 USD~ contact details here: https://stackoverflow.com/users/1067003/hanshenrik?tab=profile
