I have looked every where to find how to set up for rocksmith 2014, custom cdlc. their is not one that has worked for me. followed to the letter on all. no one goes into detail on any I have found, or does a lot of nonsense talking. if the d3dx9 dll does not work , do you leave it and add the patch?? or just the patch? Do you play rocksmith through custom forge or steam if so explain. I put the dll file in the rocksmith folder, the dlc songs in the dlc folder, just don't know. I am running windows 10/ 64 bit. could it be a setting in windows ? email me ouachitariverrat53@comcast.net , or post and send me email. I feel a lot of folks have had the same problem, bang my head on the wall, lol. Thanks DGC
