What license code? For the Radioreference site? It's showing you are a premium subscriber, you aren't issued a "code" just user ID and password that you have since you were able to post.
You still have to buy SCANNER SOFTWARE to program your scanner and you have to be a Premium Subscriber (WHICH YOU ARE) to download from Radio Reference.
Welcome to Radio Reference.
Freescan from Sixspot Software is free for programming most Uniden model scanners. With it you can log in to your RR Premium account and download systems for your area, then upload to your scanner.
