Sergey,
the easiest way to install the demo version would be to install it locally on your machine - it appears that you deployed the unpacked (but not installed) version of the database and the site. AFTER you install it locally, run the SQL migration wizard, deploy the database via it, and upload the site files via FTP.
Since you alrady performed the uploads, I think that you could get away by reuploading the web.config file of your local installed instance, but first change the connection string value in it to match the database connection settings at your Azure site.
