Calibre pluigin installation error

I tried to install calibre plugin to OMV 1.0.21. There were errors at the end of installation. So I tried to uninstall it. There were errors also.
Now system ask me to apply changer. When I click apply I have following error:

Failed to execute command 'export LANG=C; invoke-rc.d 'calibre' stop 2>&1': /etc/init.d/calibre: 36: .: Can't open /etc/calibre-server.conf invoke-rc.d: initscript calibre, action "stop" failed.

What I can do now?

regars,

I did:
touch /etc/calibre-server.conf
apt-get clean
apt-get update
apt-get install openmediavault-calibre
then updated calibre
and now when I open calibre plugin subpage i have got that error:
Invalid method parameter: '' does not match '/^[a-f0-9]{8}-[a-f0-9]{4}-[a-f0-9]{4}-[a-f0-9]{4}-[a-f0-9]{12}$/i'

This was when calibre plugin was not configured (switched off)

When I wanto to set it up and switch it on and check apply I have got following error:

I have configured calibre to use temporary hard drive (previous used with OMV 0.5 and not formated after upgrade to 1.0)

Yes:
/media/54164152-a3d3-4480-9329-67034ab1e93f

OK. When I changed calibre shared folder to:
/media/54164152-a3d3-4480-9329-67034ab1e93f/calibre
and clicked apply there were no errors. I can login now to web panel.

One more question:
If all my drives are public should I clean my mess by run chown /chmod commands on /media/* folder?
If yes what commands?

As always wery big thanks ryecoaaron !!!

Is my settings correct:
read/write to following users/system groups:
ftp
nobody
nogroup
nut
sambashare
owner: root (write/read/execute)
group: users (write/read/execute)
others (write/read/execute)
replace (set) Replace all existing permissions
recursive (set) Apply permissions to files and subfolders

ACL's
(because I cannot get to some folders on shared drives from windows PC)

I understand that - but I am talking now about other folders - just my data, photos ...
I would not mess calibre folder.
(works perfect. I imported more than 300 books)
