if you export is as a mysql document and save it in notepad (remember to change the file type to all files) save it as name.mysql. Once this is done open up your hosting and look for php databases and make sure you enter a database and user and add the user to the database with full privileges. Then after you do that go back to your hostings main control panel and open phpMyAdmin and open up the database that you just made and import the "name".mysql document into that table. One final step you need to change the silver stripe config (mysite/_config.php) and where it shows your db details enter the details that you made in your hosting phpMyAdmin. Your details have to be entered like this.
Hosting Username_database
Hosting Username_user
and localhost is fine and you just enter your password how it is in the _config.php file allready
