Scam Warning

We have recently been made aware that somebody is selling copies of "The Number Race" under a different name ("Number Magic"). This company ("DyscalculiaNoMore") is charging $49.00 US to download an illegal copy of our software, and has advertised widely on the internet using a variety of websites, using exaggerated claims about the software. The exact same software has always been FREE to download right here. Our laboratory has no affiliation with the company "DyscalculiaNoMore", which is misleading its customers and violating our software license.
