Richard,
This post tells you how to do that:

Basically, it's a way to import a previously downloaded TrackMaster file into RDSS without also going through the download process. You need to make sure the file (i.e. one downloaded by other means - within the RDSS Terms of Service - such as on another of your own computers) is placed in the proper location in the race card file archive.
Unfortunately, this method does not also create Val/Spec files - only for RDSS.
Hope this helps!
Enjoy Montana!
