Okay, check two things.
In the web console:
- Go to Manage --> Appliances
- In the "Properties" pane, there is a License tab
- What is the current state of the license?
In the virtual console or via SSH:
- Go to the APPLIANCE menu
- Run DATECONFIG
- Hit ENTER 4 times (don't enter any information)
- What time does the LEM think it is? (Is this off from your network time or time zone?)
