Usually if customs won't show up after launching RS2014 through RSInjector, it's because either the file is bad (maybe missing tones, or other problems, there seem to be lots of reason for them not to work), or the AppID is incorrect. If you purchased Cherub Rock, most of the customs here use that AppID and work fine. Occasionally you have to update the AppID regardless, even if it's already set to Cherub Rock. I don't know why, but I've had to do it before. If you didn't purchase Cherub Rock, and bought something else instead, you have to update the customs to use that AppID. You also have to actually purchase the 1 DLC file, through Steam, that you want to use the AppID for. You can't just pirate it and stick it in the dlc folder. Here's my RSInjector app (in a zip file): https://www.dropbox.com/s/un4dck5eraag4cb/Rocksmith%202014.zip Everything works great for me, so maybe you just have a bad RSInjector app.
