Hi Marc,
If the entire contents of the CMS102 folder (as downloaded) have been uploaded to a folder called 'CMS', and you have entered the correct details for your database in 'Connections/localhost.php' file, you should expect to see the log in screen by navigating to yoursite.com/CMS/admin
• Check for case sensitivity in the URL you are typing in.
• Check that the details entered for your hostname_localhost (which will probably be 'localhost'), database name, database user name and database user's password are correct.
• Check that the folders and files you have uploaded have uploaded to the CMS directory in the root of your remote site.
If this still fails, please could you post back providing a link to your site?
