Hi! I started rocksmith 2014 1 month ago and i saw custom songs on the internet,and i decided to dowland som custom song. I dowlanded some song with horizon and put it to rocksmith 2014 ,but when i launch the game i get a mesage: Warning downloadable content appears to be damaged, please delet the files and dowland agin. I did this a few time, but i always got the same mesage. So please can somebody help me to solve this problem? I've got rocksmith 2014 on xbox 360.
