You can edit the bburl in the database, but it's in the datastore table where title='options', and it's stored as a serialized array, so it's a little tricky. A less tricky way would be to edit the settings table where varname = 'bburl', then upload tools.php to your admincp directory, and use "[Options Cache]" to rebuild the datastore from the settings (you also have to upload the install directory if you've previously removed it).
