So, I was clearing my desktop because it was cluttered and must have accidentally deleted Rocksmith and Steam. I reinstalled both and all of my purchased DLC's are still there in Rocksmith, but none of my CDLCs were. I downloaded the D3DX9_42.dll file and placed it in the Rocksmith 2014 folder because it was not there. Are there any steps that I'm missing? Because my cdlcs still wont work. Thanks for the help.
