Hi Stevie,
please check if the libraries are not only downlaoded, but also properly installed.
You can check this by opening one of the library folders and see, if there are .x and .y files. If it contains .x and .y files, open the application Synchron Library Installer, and in it open this sample folder. It will guide you through the installation process.
Best, Ben
