No Project Window when importing Sequel 2/3 projects

When importing Sequel2/3 projects into Cubase Pro 8 the projects get imported with access to the Mix Console, the Control Room Mixer, the VST Connections, the Virtual Instruments, the Transport bar and probably other windows as well, but not the Project Window.

You can play and mix the project, but without access to the Project Window, it is very difficult to do any practical work on a project.

However, you can import the same projects in Cubase v7.5 and get the full functionality. Then you can save it as a Cubase project file (.cpr) and reload it in Cubase Pro 8 and continue from there. Very awkward and time consuming.

Kind regards
