We have released a new version for the GoTrusted client (v 188.8.131.52) on the new Mac OS X Mavericks. The new client fixes the known issue with Mavericks not resolving websites properly when connected to the VPN.
Any users running Mavericks should update to our new version to avoid any issues. You can find the new version on our download page here. As always, please contact support if you have any problems or questions!
