Hamachi lobby problem

Hi guys. I recently changed my old XP PC for a new Windows 8.1. I finished installing EB and all other things you need to play it online. I got the Hamachi versión from my old PC to the new one. I thought it would work just fine. And it seemed, but I don't see anyone in lobby. Apart from that all seems fine: online players in Hamachi network have green dots and everything is clean. I can chat with them. The problem is in the lobby. I know this has been a very common and difficult problem to solve. I don't know of anyone who solved it, except, perhaps, one guy from Kurdistán which I helped months ago. What should I do?
I have:

1) Reinstalled - Rebooted.
2) Modified Hamachi preferences.
3) Forwarded the Rome ports on my router

Do you think I should update my Hamachi version? Will it work with the other players?

I hope I find a solution, since Rome II is a fiasco. Thanks for your time.
