I purchased this script based on the demo on the website. But there are 2 things that they do not say :
1- uses ioncube
2- there is a check to their website so they can disable the script from the distance!
3- a lot of files are encoded, like all the globals, the cookies and more.
We were unable to run the script correctly (the capcha was not working because of some global variables encoded in Ioncube). Company is located in Malaysia, but they gave us a chargeback, so it was good on this point.
