I am trying to use HAMACHI VPN free version. However, it's been installed using a Hamachi IP from another system I have running on my network by mistake. It should have it's own Hamachi IP. I've tried uninstalling and reloading, but somewhere in the registry the unwanted Hamachi IP must always be lingering, because no matter what I do, everytime I reinstall Hamachi, whether it be a different version (like 22.214.171.124) or the current version of 126.96.36.199, the same Hamachi IP always reappears. It's giving me the error message of MEDIATION SERVER REJECTED YOUR AUTHENTICATION. Any ideas how I can cleanly, and fully unload this program so when I reinstall, I can set it up with a new HAMACHI IP?
