Please follow the manual uninstall instructions below. We want to make sure all files/folders are being removed from your machine so you can do a fresh install and see if you are still experiencing these problems.
Manual Removal Steps
1. Navigate to START-> Control Panel-> Add or Remove Programs, select the AT&T Net Client. If present, highlight AT&T Global network client and click CHANGE. Select REMOVE and select the option to remove all user settings from this computer.
Reboot the workstation.
2. Click on Start-> Control Panel-> Network Connections.
In the LAN or High-Speed Internet section find the entry for Local Area Connection.
Right click on the entry and select “properties”.
Scroll down the list of items in the “This connection uses the following items” section. Look for AGN Filter interface and AT&T Wi-Fi Support Driver
If you see either highlight that entry and select uninstall.
Reboot the workstation if you had to uninstall either or both entries. Otherwise move on to step 3
3. Click on Start-> Control Panel-> System
Select the hardware tab and then device manager.
At the top, click on VIEW and select "show hidden devices".
Expand or ‘open’ Network Adapters and look for ‘AGN virtual network adapter’ or any AGN component listed.
If either or both of these entries exist, right click on the entry and select ‘Uninstall’
Reboot the workstation if either or both entries were uninstalled. Otherwise move on to step 4.
4. Right click on START -> EXPLORE
Click on the “Tools” drop down menu, and select “Folder Options”. This will bring up a widow with three (3) tabs. Click on the center tab titled 'View'. On the Advanced Settings list you will see an option titled 'Hidden Files and Folders' make sure that the 'Show Hidden Files and Folders' radio button is selected. Click on Apply in the bottom right hand corner and then OK.
Delete the directory C:\Program Files\AT&T Global Network Client
Delete the AGNS folder from C:\Documents and Settings\"logged in user name**"\Local Settings\Application Data\

Please check each username defined under Documents and Settings for any instance of the AGNS folder including the “All Users” folder
*** We have found instances where AGNS existed under other computer names such as Administrator, so please ensure all AGNS folders have been deleted.

I show that you are connecting SSL. Can you please switch to IPSec and see if you are able to connect IPSec?
Open the AT&T Global Network Client, click on Setings, Login Properties, on the General Tab you should see Network Services, Please click on Configure and click Next until you get to the Network Screen. Please change it from Managed VPN SSL Dual Access to Manged VPN IPSec Dual Access. Please let me know if you still receive an error.
