There are several websites not exactly recommended that the owner of this website removed from more than several posts.
One website was questionable as Chessbase indicated a malware problem.
I contacted one of the programmers or owner of the site and posed the question. After over 8 days I did not get a reply.
Note that when I contacted that website in the past, they usually answered me right away.
I even purchased Chess Star books from the site.
The other website contains copy right violations.
If you need downloads or merchandise go to reliable sources on the net.
These days there are thousands.
