Dorico sound isn't working

I installed Dorico 3.5, I’m using the free trial. I downloaded a digital sound library (BBC Symphony Orchestra, by Spitfire Audio, and LABS). I see the option to use the Virtual Instruments with Reproduction. When I write something in the music sheet (Composition), I can hear it, but when I enter to reproduction, it doesn’t sound. I tried exporting audio to see if it was just an error, but even the .wav is just silence. Does somebody know what’s going on? Thanks. (If the name of any option is different or something, I’m not a native English speaker, so I don’t know if the name of some options is different in English)

BBC SO and other libraries don’t work with Dorico straight out of the box. You need to set up expression maps first. You probably better first read the thread
