I've done everything required and it's still not working. I downloaded D3DX9_42.dll and put it in the Rocksmith2014 folder, I have Cherub Rock (as well as that I have the Smashing Pumpkins song pack and the Rush II Song Pack), I've restarted my computer, I've verified game cache twice, I've restarted Steam, nothing. I'm using Windows 10 if that matters. Please help.
