Windows – Cisco VPN client failed to enable virtual adaptor

cisco-vpn-clientwindows 7

I'm trying to connect to a server using Cisco VPN client 5.0.07.0290 on windows 7 but while it's trying to secure the communications channel it comes up with an error 'Failed to enable Virtual Adaptor'.

Can anyone shed any light on the problem?
