More detailed instructions for removing the Cisco VPN client from a Mac or a PC are available at Uninstalling Cisco VPN.

Problems with establishing a VPN connection using the VPN client

Verify That You Have An Internet Connection

Try accessing a site that doesn't require VPN to ensure that your Internet connection is indeed active.

Try Disabling Local Firewalls

You might have a firewall program running on your computer such as Windows Firewall, Zone Alarm, etc. When you are trying to connect, if you are prompted that the VPN Client is trying to access the Internet, be sure to "Allow" or "Unblock".

Opt-out of Domain Helper Services

Many ISPs have domain helper services that redirect traffic, for a variety of purposes. Occasionally, this can cause problems with VPN. Contact your ISP to determine if and how you can opt-out of Domain Helper Services.
