im just making this post because i recently had the problem where my cdlc would get to tuning and then be stuck on the screen with the amps and nothing would happen. I saw a lot of questions about this on the internet and on here and basically no straight forward answers. I FIXED MINE. What i did is took all of my cdlc out of the rocksmith folder and add one by one. If your game starts doing the freeze thing at the amp screen that means you have to remove the last cdlc that you added because it is bad.
