Spamassassin doesn' t start

[SWBerlin]

I'm running Plesk 8.1 on a Suse 9.3.
A few days ago, I upgraded Plesk from 8.0.1 to 8.1.
Since that day, spamassassin didn't work anymore. I reinstalled it two times, but there's still the same error when starting it via Plesk:

ERROR: PleskFatalException
Unable to make action: Unable to manage service by spamd: Command line usage invalid.
0: /usr/local/psa/admin/plib/common_func.php3:153
psaerror(string 'Unable to make action: Unable to manage service by spamd: Command line usage invalid.')
1: /usr/local/psa/admin/htdocs/server/restart_services.php:28
[/php]
I'm not well versed in linux, so has anyone an easy solution for me?

Thanks a lot,
Florian

/etc/init.d/spamassassin start

Unfortunatally there is no file spamassassin in /etc/init.d/ .
The file that comes close to spamassassin is "psa-spamassassin", but this one somehow dosen't work with
psa-spamassassin start. It says "command not found", but with vi I can see a command for "start" that goes to "spamd start".
