I've just installed LimeSurvey 1.85 - upon first access to http://MYDOMAIN.COM/adimn, I get a message saying:
The LimeSurvey database is not up to date.
Please run the installation script to upgrade your database.
the link points to: http://MYDOMAIN.COM/admin/install/index.php
which returns a 404 error, because the install directory is already deleted...
