Hi Lewis, welcome to Pace and Cap, and to RDSS!
In the RDSS Data Centre, did you Convert your card (DEL, tomorrow?) to the Database? If so, your screen might look like the following:
Since today is June 16, and the card is for tomorrow June 17, open up the
Future section of the Sidebar and you will see tomorrow's data and the DEL card under that date. Double-click the DEL card for June 17 and the Card Summary screen will open, from which you select a race to work on. In that race, open the PPs by clicking on the Past Performances button, then take it from there, according to the various tutorial videos (but feel free to ask further questions
)
Hope that helps!
Ted
