BBES The current design file is not an electrical design file

Hi

       I have just installed AECOsim SS5 to evaluate. I have launched aecosim electrical, created a new file from default seed file.

When I go to use any of electrical design tools the message centre displays the following text.

BBES The current design file is not an electrical design file

scrolling down in message centre also contains error.
