cant connect with hamachi

so i used this back in july to play dungeon siege 1 with a buddy of mine on multiplayer because i never got the chance to prior. Hamachi would connect just fine. But now, it absolutely refuses to connect. I've reinstalled it, i've deleted the drivers, and everything and it still just sits there on the menu with the power button lit up, and it says 0.0.0.0 reconnecting... and after a minute or two, it'll say that my server connection is offline, which isnt true because my internet connection has never really failed before. And then the follow up message will be: Failed to connect to the Hamachi servers. Would you like Hamachi to
automatically monitor server availability and establish a connection as
soon as it becomes possible ? Regardless of what i press, nothing happens.
