The configuration has not yet loaded after removed interface

Hello,

I have BIG IP VE launched in Amazon AWS.

This machine had 4 network interfaces and recently one of my colleagues detached and deleted one interface in amazon aws. Since then BIG IP Management WebUI shows a message:

The configuration has not yet loaded. If this message persists, it may indicate a configuration problem.

I've tried to reset BIG IP to factory defaults using this command:

tmsh load sys config default

And got the following error:

Unexpected Error: ltcfg error, can't load class, class:"system" 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.

Then I've executed this command:

tmsh load sys config

And got the following output:

Any ideas how to fix this without loosing licence key?
