I've been playing some games with my friends about 2 months ago, then hamachi messed up and gave me the cyan circle next to my friend's name, same thing happened to him. I'm looking for solutions for 2 months, still nothing has helped...
I've rebooted my router... I've reinstalled hamachi, I've looked at several youtube videos and nothing has worked.
I'm running Windows 7 and I hope there's a solution...
