Apologies if this was covered anywhere else. I searched around but wasn't able to find the same problem.
I used the tutorials and the Con tools to set myself up with some custom songs, and they work beautifully. The only problem is, I can't play any of my DLC songs. They show up in the list, but have no album art or preview and give me the "Unable to load song" message before quitting out.
I tried downloading the Title 5 update and they worked under those conditions, but reverted back to not loading when I deleted and reinstalled the Title 4 update. Any help would be greatly appreciated. I'd love for the entire library to be working together.
