How do you refresh the model in layout

I have tried all the above and have got nowhere but highly cheesed off.
Besides all the sign in and out I would like to know how the Document set up supposed to work. I can not get it to purge or reconnect.
And for the 10th time I am again told I am unlicensed, what a pain this Trimble system is on that score. Another day I could have had an achievement. Lost due to software issues.
