He guys I just tried out your nifty tool - I like it so far, but Customs song wont play after retuning the guitar. After retuning, the lights fade out and thats it - RS stops working. Alt F4 still works. Any ideas? Thx in advance As requested: I tried with 4 songs of Ed Sheeran; same problem. Never played before I downloaded them, moved them into my DLC folder, apparently the show up, DLC ID seems to work .net is up to date, read some stuff here and watched 2 or 3 tutorials on youtube Other, officially steam-downloaded songs still work FIxed it with RS_Patcher THX
