MOH and Recording do not work

In the module MOH are no melodies and I am not able to upload files:

Error Processing: “sox: Can’t open input file ‘/var/lib/asterisk/mohmp3/orig_drama.wav’: No such file or directory” for drama.wav!
This is not a fatal error, your Music on Hold may still work.

Also not able to create categories

I was thinking to reinstall the module but it is not possible from the module section

Can someone help?

Also all recordings I enter cannot be plaied.

Did you ssh into the server and verify that you have a /var/lib/asterisk/mohmp3 directory? It wasn’t on my system and I did an install from AsteriskNow.
