I'm working on a mac and recently downloaded the Cisco VPN Client from my company's internal site and when I try to open the application, the icon shows up in my dock and I get an error message saying:
Error 51: Unable to communicate with the VPN Subsystem. Please make sure that you have at least one network interface that is currently active and has an IP address and start this application again.
Do I need to setup a network interface? Any suggestions are appreciated!
