I can confirm it still works today with: Rocksmith 2014 Remasterd + one official DLC that was packed with the software I bought (not Cherub Rock in my case, but Bob Marley - Three little birds) + Song Creator Toolkit 2.9.2.1 (2019 version downloaded today) + the explanations given in this thread to check which DLC you already have, before purchasing a new one, take a look at: C:\Program Files (x86)\Steam\steamapps\common\Rocksmith2014\dlc in my case I have 13 files e.g. bobmthre_p.psarc
