I recently installed Windows 7 on my Sony laptop. I had previously been using Hamachi 2 VPN to access a remote server. After installing 7, i get an error within Hamachi that says "Hamachi Adaptor Error, Peer is not accessible via VPN" After running diagnostics I also get a message that windows is unable to download the needed driver. Hamachi is installed and I'm able to see and chat with other members of the network, but can not access the network files. help!
