Hello, I have the same problem. I have followed instruction given in the video to install the CDLCs. The dll D3DX9_42.DLL is copied under the root folder of RS2014, I have the official version of cherub rock song and I have used RocksmithToolkitGUI.exe to change the package ID of the CDLC song. I have tried also with Rocksmith2014_patcher.exe copied also in the root folder of RS2014. The result is always the same (I have tried with several CDLCs with _p.psarc extension as I have a PC under WIndows 8.1): I see the CDLC song, I tunne my guitar and once done, nothing. Only the 2 amps but the song don't start. I cannot even go back and have to kipp RS2014 process. Note that RS DLC (and cherub rock) are working correctly. It is only CDLCs which don't start after tuning the guitar. All ideas to find a fix is welcome. Thank in advance.
