I dont have it installed and I have never installed it but there is an instalation.txt file in the docs folder, always pays to read the install info
a general rule of thumb here for you all.
if the document gives access denied when you are trying to upload something it usually always means you have not set permisions to a folder where you are attempting to upload it.
if you get a permision denied while simply trying to run a script that has nothing other than page view it is most likely permision seting on a file.
