F1 2010 Problems playing via Hamachi

[Rigel]

Hi everyone. I've got a problem trying to play online via Hamachi with some friends of mine. I manage to find the room and enter it, and even reach the track. But, once the track is loaded and the session is starting, I get kicked: "*host name* has abandoned the party: f1 2010" (or something like this, I'm translating it from Italian). It's only me having this problem, my friends can easily play.
We all run fresh installed game with 1.01 patch, no mods at all. I also tried changing router, deactivating antivirus and NAT, and still no results. Any suggestion?

I bought it. Actually, one of those friends of mine didn't, and he can play without problems.

You could use tunngle. Its like hamachi but has a better interface, is easier and so on... just google for it
