GUI does not popup with an error message indicating it has expired. The only
indication you have is in the log file.
A message does appear if you are using the VPN Client command line -

If a ZoneLabs product such as ZoneAlarm or ZoneAlarm Pro is installed on
the PC and the VPN Client is installed or upgraded, ZoneAlarm blocks the
VPN Client service (cvpnd.exe). The VPN Client’s splash screen appears, but
the GUI does not. ZoneAlarm does not ask the user whether to allow the VPN
Client to access the Internet. Additionally, the following error appears after
about two minutes:
“The necessary VPN sub-system is not available. You can not connect to the
remote VPN server.”
Workaround:
Do the following steps:
Step 1 Open the ZoneLabs product and select “Program Control”.
Step 2 Click on the “Programs” Tab
Step 3 Cisco Systems VPN Client's Access permission is a ?. Click under “Trusted” and
select “Allow”. The ? mark changes change to a Check mark.
Step 4 Reboot the PC.
