HELP! I also cannot get this to work. I was sent the key in a text file but there's no way to insert it as it's looking for a *.rlicense file.
But I only have an attached key.txt to the email sent to me. I originally did register by pasting the key. But something apparently happened and now being told the trial is over and to register again?
I did delete the config_4.xml file, but it's only wanting the *.rlicense by asking for it's location.
