I followed your procedure and downgraded to version 126.96.36.1999. It's fine but I get RPV error and cannot ping another peer online in the same group, bothe associated to the same logmein account. Nothing change after I reboot both device. I guess it's a tunnel issue to a too old version. Then I decided to follow the procedure again with version 188.8.131.52. It seems to work.
What is weird is hamachi kept all settings except auto-update turned to ON, then forced to create a new peer, get a new IP and join a network again. The update to last version 184.108.40.2069 was done automatically before hamachi go online and I create a new peer. So I am stuck withe the last version.
