Not to hijack your thread, but Im having the same issue since I updated the Rocksmith Toolkit. Not sure if Im misunderstanding how to use it, now that the UI has changed, but Ive used CDLC without any issues up to this point, so Im not quite sure why this isnt working for me. http://imgur.com/Eim9wN0 Yes, I own Aces High(its the ID Ive used for all my CDLC), and Ive updated the .dll after the Remastered update. All my 'old' CDLC is still showing up, and working. The correct way to do this, is to choose a song I own and RS2014 in the AppIdUpdater, hit Repack AppID and pick the CDLC I'd like to update, correct? Then put that update in the Rocksmith DLC-folder, and thats it, right? Then why arnt the CDLCs Im trying to add showing up in-game? This is driving me mad, I need some new songs in my life, and the official DLCs havent been to my taste in a while now.
