I've downloaded the trial version of City Engine and would like to publish a 3d scene to ArcGIS Online, but the File -> Sign in option is greyed out, along with 'Share As..' and 'ArcGIS Online..'

I have set the proxy server under Preferences, and when I go to Help -> Download Tutorials and Examples, it does load the list of tutorials and examples, however when I select something to download I get an Error which says:
'Downloading Tutorials and Examples...' has encountered a problem.  As I'm not getting the 'Cannot connect to internet' error I get when I don't have the proxy set, I assume the connection is ok.

I am however able to sign in to my ArcGIS Online account in ArcMap on the same PC.

Is the ability to upload to ArcGIS Online unavailable in the trial version, or is there something else going wrong..?
