Xbox 360 Where exactly do I make new folders and place CDLC

I have a JTag / RGH modded Xbox 360 elite box.  I have a Rocksmith 2014 disk and was able to load it on the hard drive.  I can play Rocksmith 2014 from the Hard Drive or from the disk.  What I cannot seem to get correct is where to place the new folders that I must create to get the Xbox to play the CDLC.

I have placed in on Hdd1/Contents/0000000000000000/555308C0/00000002

The 555308C0 is a zero at the end correct?

I placed Cherub Rock.xvbox in the folder and another CDLC I converted.  They are there but Rocksmith does not see them or place them on the playlist.

Any help is greatly appreciated and if it works I will send you a check for your time.

Thanks,
