Date index for Dec 2002

Thank you.  I can now manage to log in with "administrator" and "demo" and
nothing else.  It loads the achievo index page but at the bottom of the page
i get in red text the following message:
error:  cannot use database achievo_0_8.
error:  No Database Selected (errno:1046)
error:  Invalid SQL:SELECT theme form employee where userid="administrator"

with a few similar following.
I have gone through the INSTALL file in achievo/doc and followed all the
steps.

Any ideas?
