HSSE loses patches exchanging projects Cubase->Elements

I have Cubase in the studio and Cubase Elements 7 on a laptop and although I can exchange project files between them, if I create a Cubase project with a MIDI track sending to HSSE, when I load that project into Elements the patches are no longer selected in HSSE and must be manually re-loaded.

I limit the projects to use only the “Basic” set of patches that is common to both Cubase and Cubase Elements.

Going the other way is fine – if I load a project from Elements into Cubase (7 or 8), the patches are still selected in HSSE and the project plays OK.

Has anyone else had this problem? It is now an issue because I want to collaborate with another musician who has Elements, sending (small) MIDI-only .CPR files by email.
