Terry, this could be one reason for that error message.

When you launch your vpn client and setup a new VPN profile, you have to enter the tunnel group name you configured in ASA RA vpn and enter the password which is the Pre-shared key you also configured in ASA.

Did you created a new tunnel group or are you using the default DefaultRAGroup? I would recommend you create new tunnel group to keep it separate from the default tunnel group, but if you are uing DefaultRAGroup this is the first login pop up you get when you connect to ASA from the vpn client.

If your tunnel group name is DefaultRAGroup, and know the Pre-shared key, you enter the group name and the pre-shared key as a password , when you pass tunnel group name authentication,then another authentication window will pop up which then you will use a user name and password you have configured in ASA users accounts in device management Users/AAA. What I believe is happening is you are entering a user name and password as suppost to tunnel group name and password and that is why you are getting that error message.

Let me know if this helps or not, we may then take a different approache to solve the problem.
