I can't ping him, when I diagnosis him I get:
Tunnel: OK
Local results:
Adapter configuration: OK
Traffic test: Inbound traffic blocked, check firewall settings
Peer results: [189-689-694]
Adapter configuration:
Cannot get adapter config
Traffic test: Cannot complete test
If he clicks the yellow triangle he it says there's a tunneling problem and if he keeps clicking more details he gets network adapter error. If he runs as an admin while the service Hamachi Tunneling Engine is stopped he gets a diagnosis saying that the hamachi service has stopped (which makes sense) and that all required files are found but for the Driver it says the Hamachi client needs to be reinstalled. If he clicks details, he gets 'inconsistent timestamp'. We're tried restarting, uninstalling and various other things but nothing has worked. Also I (the network owner) can connect and play with other people so I don't think it's a problem on my side.
We're both using Windows 7 and probably the latest version of Hamachi since we both re-installed.
Any help?
