I am running the Cisco VPN Client 4.7.00.0533 to connect to our corporate network. I installed the Adtran NetVanta VPN Client 10.7.2 to remotely access client networks. Since doing this, the Cisco VPN software will not work. When I try to start the vpn, it says the Cisco VPN service is not running. If I start it manually in services, it stops again instantly. Any ideas?
