I installed Hamachi and Hamachi-GUI, on both my girlfriend's PC and Netbook. After 5 minutes or so (even if i keep using it during that time) it loses its online-connection. I have to go offline, then online again in order to see my ip again.
If i don't and I ping my IP, it says
Host unreachable. Now when i connect with my Mac from the office the problem doesn't exist, so i wouldn't say it is a problem of my "Hamachi (server) installation", and i am tempted to say, it is a problem of my girlfriend's connection, since it happens from her home, and we haven't tried yet to connect from another home with her setup.
I followed these instructions. What would you say?!
