Problems when opening Cubase pro projects on second computer (with vienna ensemble pro)


When I try to open a Cubase Pro 12 project that I copied from my desktop to my laptop, I get the following error:

The project’s vstis are hosted by vienna ensemble pro (on the same computer). I then get this error:


I don’t understand why Cubase does not recognize the ports that these VSTis are connected to. There are not any problems on desktop.

Thank you!
