LMS does not start after moving to new USB disk on piCorePlayer

Hi

I bought a new ssd for my piCorePlayer (I want to eliminate moving parts) and copied all due Music and server cache data (after shutting down LMS).

Now the LMS doses not start anymore, not even from the original LMS cache / data.

I get the following error:

```

What is going on here?

Thanks,

Rainer
