The script has potential, but unfortunately the entire thing is encrypted which makes it impossible to debug (which you'll need to do) or modify.
I've spent the past 4 hours trying to debug something but it's impossible due to all the files being locked up tighter than a drum.
If you're buying this, don't expect to be able to customize it or check it for security flaws.
Oh, and one other thing - the documentation is non-existent. You get a text file with a few installation instructions and then the rest is left for you to figure out by yourself.
I've been programming for over a decade so fortunately I am able to do this, but if you're not at the same level you're going to be struggling quite severely with this piece of software.
