so, I got email about update hamachi to 0.420 that supposedly to remedy my situation. but unfortunately, it is not.
the yellow triangle is still there.
what's even worse, just yesterday, suddenly hamachi acting up again, and several computer with windows 8 64 bit that's ok before, now is not. it stuck on "connecting" for along time, and then there would be error msg "Failed to connect to server", and a question asking if I want to wait and reconnect again and again. For about 2 computers, this helped and it would connect even though having to wait a long time, for another 2 computers, it was not. it would still saying "connecting" or "reconnecting" and wouldnt connect at all.
This great program is suddenly not great anymore.
it's a nightmare that I think I would better learning how to program microtic to setup my own vpn (I would if only I have more time to spare).
