Thanks for the response.

The scripts M10, M20, ... are not marked as executable and should not. But the scripts M30, M50 and N10 are marked as executable (chmod 755) but are not executed.

My configuration is a single hard disc.

With the swap file I have no idea, found nothing useful in the FAQ.

When trying to access files in the programs0 folder whether rwm nor rw helps. The error message is alsways read-only.

Anything else I could try?
