The newest version is working perfectly for me! If you are still having trouble and getting errors when using PIA try the following...
1) Download the new "NextGen" OpenVPN Configuration files from: https://www.privateinternetaccess.com/pages/download#
2) In your appdata folder replace the following files from the configuration files you just downloaded:
appdata/binhex-sabnzbdvpn/ca.rsa.2048.crt
appdata/binhex-sabnzbdvpn/crl.rsa.2048.pem
appdata/binhex-sabnzbdvpn/***.ovpn (*** the server of your choice)
3) Update the container with your PIA username and password (NOT the PPTP/L2TP/SOCKS username and password)
4) Restart SAB....you should be good to go.
