Big-IP Confiuration Utility is not working

Okay. I'm having a similar issue on a 1600 Strongbox running 11.4.1 GUI not accessible. License reactivation from command prompt shows: License is not operational (expired or digital signature does not match contents) Last Service check date was 2015-08-20 and I have no support contract active.

From the discussions above, seems the support Contract is the main cause of the license failure??

The command : load sys config base gave the following output:

admin@(bigip)(cfg-sync Standalone)(LICENSE EXPIRED)(/Common)(tmos) load sys config base
Loading system configuration...
  /defaults/asm_base.conf
  /defaults/config_base.conf
  /defaults/low_profile_base.conf
  /defaults/policy_base.conf
  /defaults/wam_base.conf
Loading configuration...
  /config/bigip_base.conf
  /config/bigip_user.conf

Unexpected Error: Loading configuration process failed.

and the command load sys config default yielded this:

Unexpected Error: ltcfg error, can't load class, class:"password_policy" error: can't load class definition from mcpd. This is most likely the result of a failure to load the base system configuration. To determine the root cause enter "tmsh load sys config" and include the output when the issue is reported.

Can we conclude from here that the absence of support contract is the issue here??
