Hey there bud,
I finally got mine to work. What i basically used a suggestion from earthsaver:
1) Uninstall hamachi using the uninstaller
2) Go into Library/Application Support and drag out the Log me in Hamachi folder (or just delete it)
3) Reinstall Hamachi
Immediately after the installer, Hamachi will crash and throw an error message then quits. Dont be alarmed, I just reopen it, Activate Hamachi, then it will ask you to join your network again (because you deleted the config data previously).
I also quit hamachi, reopened it, forced quit, reopened, Disengaged VPN connection, re-engaged, and still worked perfectly. So my theory seems to work.
Let me know if this works.
