Hi,I have purchased the 737NGX and the install was fine. However, it turned out I had to install the Direct X program, in which would not install because the cabinet file, needed for installation is not trusted. It also says I need to find out if the Cryptographic Services are enabled and that the cabinet file certificate is valid.I'm not a genius over this. Any help over what I can resolve. What do I do?Peter
