[Spambayes] Ver 1.0.4 (downgrade from 1.1a1) sb_server.py start error

[Vys0]

Hi,
as I lost my database again (using 1.1a1) I tried to downgrade to 1.0.4 today.
DL'ed the tar.gz file, untared, made:
python setup.py build ---> OK
python setup.py install ---> got erros with write permissions - "su -" and 
python setup.py install again - this time everything seemed to be OK. Got 
back to normal user (with "exit").
Tried to run the server - and got this:

[vys0 at agnich ~]$ sb_server.py
SpamBayes POP3 Proxy Version 1.0.4 (March 2005)
and engine SpamBayes Engine Version 0.3 (January 2004).

Loading database... User interface url is http://localhost:8880/
