Insurance Balkans - Montenegro, Bosnia (again)

I know there have been a few threads on this but trying to get the latest info. In 2009 we traveled through the Balkans and had cover for all the countries (named on a green card) issued by Groupama via Carole Nash. It seems that Groupama have this year restricted the countries that they issue green cards for - for instance, Morocco used to be covered but isn't any longer.

So, here's what I have:

Slovenia - covered automatically
Croatia - covered via green card
Bosnia - covered via green card (green card cost for the above two was �36.00)
Montenegro - no green card available
Serbia - no green card available.

Has anyone found away of getting a green card for Montenegro, or recent experience of getting one at the border?
