If you are using a new version of Trainz, meaning TANE or up, you may have issues installing this route into your version due to the trees. Older Speed Trees aren't compatible with the current versions of Trainz. You should register your Trainz version so that the version appears on your timeline. That helps us a lot to show you are in fact registered. If you already have registered under a different username, or are using a Steam version, contact the helpdesk via the link above and someone will fix that for you.
