My friend has been having problems with Hamachi. The same old problem with Hamachi that you always see. Mediation server has rejected your login request. He's tried the rename the whatever it is folder method. He's also tried the special fix method (the one you use if you've downgraded and re-updated, which he never did anyway.) Anyone have any other solutions that might fix the problem? Also, if you can name another LAN emulator, that would also be great.
