Beijing 2008 on Windows 7 with LogMeIn Hamachi (free)

Hi,
we want to play Beijing 2008  (Sega) by using LogMeIn Hamachi. At hamachi all signs would say it will work, but at the game we dont see created games of each other. We have tried to turn off firewalls and so on, but we´ve dont find a way how it works.  Since 3 or 4 years ago everthing works easy.
Thanks for your help
