Seems to be a NIC issue. Disabling Hamachi and then disabling the card followed by renabling the NIC seems to get me one go on Pro E before I need to cycle Hamachi and the NIC again. I'm going to look into a new driver for my NIC, and maybe removing Hamachi. Thing is, I've had Hamachi on here for a month before the issue started. I also have Hamachi on the laptop, although lately that computer has been behaving most of the time.
