You could try reading the documentation. There is a whole section on troubleshooting installation issues: http://www.nbill.co.uk/help/index.php?page=blank-screen-after-install.html. Also, if you use the free trial of the standard edition, you get free support - I would have installed it for you if you'd only asked. There was no need to leave a bad review.
