AT&T Network Client - IBM is not working

Hi,

Today I connected to the IBM vpn, after around 30 minutes I was disconnected and the Connect/Disconnect button and close the window and when a I opened again it didn't show anything inside. I'm attaching a screen shot. I also checked the logs an I saw this message:
The file 'C:\ProgramData\AGNS\NetClient\WiFiAuth.txt' could not be read.

I looked for this file and didn't find it.

Can you please help me?

Thanks in advance for your help.
