You should be able to edit the three CSV files in User Settings – Check out this YouTube video for more details https://youtu.be/ml5DBvXvrEg
We did have an issue initially but it should be corrected, depending upon the time you downloaded the trial. Do you see icons to the right of each CSV file? The “Choose File” icons to the left allow you to import your own CSV file (or view the one currently there) and the icon to the right allows you to open the folder where it is located and edit the file directly, save it and it should be good to go from there.
Again, you may need to update to latest version, and please excuse the hurdles on first launch, we just went live a week ago.
