So as the title says, a good 45-60% of my cdlc stopped working at some point and when coming back to the game has been a real source of frustration. Issue happens when selecting a cdlc track, the game will freeze on the spot. Happens on multiple PCs. Even set up a new micro pc (disconnected from internet, fck off ubisoft updates) because my main setup started having an issue where my sound device was not being detected leading to no sound coming through the game. Weird issue but my main concern is the songs. Im piecing together the need for the Customforge Song Manager but havent found a good guide or really others having this issue (at least that I can find)

You don't need the song manager, just running the enabler from the Use CDLC link
