It's my first time using live2d. I've downloaded cubism editor 4.0.06 just yesterday so I'm using the free mode/free trial mode. When I tried opening the file today, it just didn't work! I also asked a friend to try opening it on his computer and it didn't work either...
Here's the error I found in the log:
