I tried to find a old topic with my problem, but I really do not know how I can search it.
Anyway, with some custom songs, the game crashs when I launch them (i.e. Black Sabbath's Paranoid or Halestorm's I miss the misery)
For both, there is a lot of bonus tracks I can choose (with glitches in the left top corner where I can choose the bass bonus track ), but when comes the moment I enter in the song, it crashes. Sometimes, I can play them, but I do not know how and why I could.
I have the last dll version, on PC Rocksmith remastered.
