Thanks to everyone who already asked questions and equally to those who gave so many excellent answers.
Installed and working fine (I think) just need some traffic and conversions to test it.
Install on Zen cart v 1.5 fresh install with a renewed cleansed database, which was one of the biggest issues I faced with this as the uninstall script did not seem to remove all of the tables and data from the older version I had install on Zen cart 1.3.9.

Thanks again for every one involved.
