@Saint Hmm. If you chose Menu --> Reports --> Todays Flights | Yesterdays Flights, you absolutely should see something. Are you sure that whatever feeds your VRS was feeding it on those days? Maybe it wasn't connected? Do you have the webadmin installed? If so, browse to the webadmin URL and log in. Then go to the Connector Log and see if the receivers you had set up were connected to the source during those days.
I rarely have ever used the Freeform report, so it might be tricky to put the right criteria in and not accidentally exclude what you are looking for. The Todays/Yesterdays flights definitely should give you info. If not, I have to wonder if your VRS is writing to the SQLite database.
