Just tested it on an even newer version of PHP and it is failing to setup the required table in MySQL!
So it needs an update. I will get to it SOME time.... when?!? Not for some time. But if you want to fix it and let post it I will add it to the main release.
If you are interested i knowing when I issue a new release follow me:https://twitter.com/#!/dwalkercouk
