Sorry, worked it out just a case of me being knackered and having a dead line of tomorrow to finish the site.
When I navigated to www.name.co.uk/SecurityPro_installer.php the first time it didn't fully load. But it had added some bits to the Database, if I had been a little more awake I would have noticed that there was a second page or rows for my 'config' database. Deleted the two that had been installed. Re-installed, first time with no errors.
Sorry for wasting you time.
Regards
