Sorry, we had some trouble connecting to get templates and can’t show them right now. This message might be displayed within the Project Professional Client, if you try to open the enterprise project templates from the Project Server, even if the permissions are set up in the right way.
Good news: It is easy to fix!
Open Project Professional, go to File -> Options -> Save and enter a location for the default personal templates. It can be any local location, that doesn’t really matter. Close Microsoft Project and open it again – you should be able to see the templates, now!by
