Thanks so muchNaviga to A:, press R+A on "title" folder and select "Search for titles". Once the search has finished, you will see a list of everything you have installed; in your case DLCs are at the bottom of the list and start with "00040008c"; press on the .tmd file associated with the DLC, go to "TMD file options" and choose Build CIA, either Standard or Legit (I think legit is for DLCs that you really bought it)
