I get similar behavior on one computer I have set up for a friend. He has 3 computers in his local network, and one of them is constantly disconnecting from the Hamachi network, usually at night. When that happens, I have to connect to one of the other computers, log in to the problem computer (via TeamViewer), and simply power on Hamachi.
Did you ever get any feedback from anyone at LogMeIn?
Below is a portion of the log from the offending computer. I powered on Hamachi this morning at 9:14am. You can see from the entries prior to that, that it looks like something went south sometime earlier in the night, or yesterday evening. I'm not sure when Hamachi was last online for this computer.
The system is currently running Hamachi 2.2.0.385, but this has been happening for many, many versions prior to that.
Thanks,
Brian
