"Configuration problem" when setting up a trial LTM VM

I have downloaded the 90 day trial version of LTM VE and am having trouble configuring it. I have installed it on an ESXi server and run 'config' to set up a static IP address for the management interface. However this is not persistent - if I reboot the VM the IP address gets forgotten and I have to re-enter it.

Next I managed to log into the UI and install the trial license. However the UI then displays this message when logging in:

This BIG-IP system has encountered a configuration problem that may prevent the Configuration utility from functioning properly.

To prevent adverse effects on the system, F5 Networks recommends that you restrict your use of the Configuration utility to critical tasks only until the problem is resolved. Beware that attempting to modify your configuration in this state with the Configuration utility may cause your configuration to be overwritten.

and when I have logged in I get this across the top of the page:

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

and most UI options just show the message "An error has occurred while trying to process your request."

So what have I done wrong, and how do I fix it?
