Titan Quest Internet play issues!

[Toushiro]

When i go to the Titan Quest Internet lobby where the servers are, i choose one to join, the loading screen comes up but after a little while i get kicked back into the lobby with the message "Unable To Connect". I get this all the time no matter what server i join, and yes i have the original version of Both TQ and TQIT. So why is it like this?

Me and a friend had this problem. We were playing via Hamachi virtual network. The problem lay with him using Vista. You have to download an older version of Hamachi to make it work. I think it's 1.02.
