Check availability of your sites

You buy a video that tells how to check your sites for availability for free. Checking sites is carried out using the script, which is freely available, so again, sold the author´s video.
Product is a text document which contains the password of THE RAR archive https://yadi.sk/d/4dZSlq7e3Xb8F2. In the archive you will find a video and a script file in the format *.php, which is a bit modified by me.
Claims and returns are not accepted, the script can be found in open sources, the script works, it is seen in the video.
