Maia doesn't recognize languages packs and themes and Spamassassin is down as status

[DaSilva]

I have just installed Maia / Spamassassin / AMaVis with the tutorial.
Spam mails are correctly recognized but the test virus mail with the text

X5O!P%@AP[4\PZX54(P^)7CC)7}$ EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

goes in the directory "non-spam cache" instead of "virus cache".
Protection level is set to "High".
In the ispCP the server status says Spamassassin doesn't run but AMaVis runs.
What could be the problem?
Thanks for help.

2. Small other problem: Users cannot use another language than english. In the settings there is only the entry "English" even if the german language pack is installed, too (at /var/www/ispcp/gui/tools/antispam/locale/de). Same problem with themes. How can I fix this?

3. Why is Spamassassin down in server status but running on the server? What must i do to solve this problem?
