SpamAssassin not working anymore after upgrade

[UncleP]

Since I've upgraded Plesk from 7.5.2 to 7.5.4 SpamAssasin won't start anymore.

I get this failure:
0: /usr/local/psa/admin/htdocs/server/restart_services.php:28 psaerror(string "Unable to make action: Unable to manage service by spamd: Unsupported SpamAssassin version: 2.55 1")

I tried to restart it manually but that doesn't work either.
My server is running FreeBSD 4.9

When I look in the CP at Component Info it says i'm running SA 2.6.1

Do I have to upgrade Spamassassin myself?

I just got the same error on CentOS3 and PSA8.1 any ideas?
