On the menu screen i get a constant "Steam API Init Failed." error. https://i.imgur.com/RFVSG3i.png Please help.

Wanted to try out something from the workshop, but can't seem to get it to work. I get that for legal reasons you need to download the music separately and put it in somewhere but neither the music folder nor the actual workshop folder seem to detect the track. I tried renaming it to a bunch of sensible things too, such as level name and just song name (no artist) I'm using the "Insane Defect" level as a testing ground...

진행 상황이 초기화된 것은 공지를 통해 인지하고 있었으나 튜토리얼을 진행하지 않고 화면 우측 하단 붉은 버튼을 누를 시 모든 조작이 불가능한 이슈가 있습니다. 추가적으로 전버전에서 클리어한 스테이지를 언락해 주시면 좋겠습니다... 진행상황 초기화를 통해 보상 또한 다시 수령 가능하게 한 취지는 좋지만 이 스테이지들을 다시 시간 들여 깨야 한다는 점이 피로하게 느껴집니...

Help me plz!!!

Wanted to check out what's new in the update, but turns out the game forgot I already played through all the songs and completed them. Is there a way to fix that, or do I have to replay everything to check out the new songs after Re:Flexer?
