I have Rocksmith 2014 remastered for Steam. I've have tons of CDLC installed that have been working fine until today...i reinstalled the games and CDLCs and no luck...

Any ideas shy this is happening?

Thanks!

Total n00b here…I'm not clear how to install the DLCS onto Xbox 360. Any help or links to a more detailed tutorial would be greatly appreciated.
