It seems acces to database is not correct.
Check config in parameters.php file.

OK.
You are on first steps of installation.
Your database is empty, and possibly does not exist.
Check that database exists and is empty.
If it does not exist, you'll have to create it manually, as you use a hosted space, and your provider will rejet automatic creation.
If it exists and is not empty, possibly you use it for another application, so use dedicate paramDbPrefix to avoid conflicts
