hello everybody   I bought a new pc today. I re-download steam ==>ok I re-download rocksmith remastered ==> ok I retrieve my profile ==> ok i copy-paste my dlc directory from my old computer to new one ==>   I can see all the songs in the game, but some songs are no playable. I mean that I can select them, and when I press Enter to play them, I can see the screen with the strings and the speakers on left and on right, but no sound, and no display of what I have to play....   Can anyo
