Since
LRC does not start until
July 3, no cards would be available yet. Please try closer to opening day.
If you can see
BTP (Belterra Park), you should see
OTP (Oak Tree at Pleasanton) since they were included in the same update file I posted in Post #1 above.
To find OTP, click Display Available Cards, then check ALL tracks in the all tracks list (use the checkbox in the header). You should then see OTP. Right-click to edit the name then deselect the cards you don't want (or deselect ALL then reselect those few card you want).
The track code update file I posted for LRC has the same name but different contents. RDSS expects a file of that name, and processes the contents if it finds it.
Let me know if you need further help.
