I have had 2012 since the beginning   I was wondering is there a mod fore it also like 2014. Just curious

Hey CustomsForge,    I bought the disc import, and for a while i had the songs in my library in RS2014. But then one day I noticed they were no longer there. Any advice on what i did and how i can fix it? Is there a way i can redeem the disc import so i dont have to pay again? There isnt a receipt on steam for it by any chance, so i can redeem the disc import again?   I may have accidentally deleted the folder ( i like to keep a clean cdlc folder, and i download an obnoxious amount of cdlcs)   

Hello!! I need help. I bought Rocksmith 2014 and im playing in on my mac. I want to have ALL the songs from RS2012 + DLC in my game. Can someone please walk me through how to do it? thank you!
