Cisco VPN Client error 51 - Mac OS X and the fix

So after installing the latest version of Parallels my Cisco VPN client broke and would give the following error on launch:

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.

I tried uninstalling Parallels and reinstalling the VPN client, still no go. After doing some digging around, I found out how to fix the problem so I figured I would post it since im probably not the only one having this issue.
