VPN client will not open or connect

Question

Hi,
I'm running VPN Client 5.0.07.0440 on a Windows 7 Pro HP TouchSmart. The .pcf file is the same iI am using on many other machines om this same network.  When I double click the icon, the window opens up, but when I double click the connection entry, the dialog box says "connecting to security gateway at xxx.xxx.xxx.xxx for a few seconds and then says "Not connected."  I can't even get to the log-in screen I normally can. This is a new computer set-up. All updates are downloaded for windows. 
I've uninstalled the client and re-insatlled it re-booting after every step. I've pinged the address and had no problems. Running Avast, Malwarebytes as on other machines. No other security software. My VPN is enabled in my Network Connections. 
Here is my log file:

I know the names and passwords are correct as they were copied from working files.
Hope this is posted to the right group.
Never had this problem after many machines. Any help would be greatly appreciated. 
Thank you

Since you're getting the message "may be configured with invalid group password", perhaps your pcf file got corrupted. 
I'd recommend you compare the profile pcf file (stored in "C:\Program Files (x86)\Cisco Systems\VPN Client\Profiles") on the non-working machine with one from a working setup.
They can be examined in a text editor or with a diff tool (like the freeware ExamDiff). The encrypted group password hashes (string in the file preceded by "enc_GroupPwd=") should match.
