Nice to meet you, again. ijoylee
tl;dr
Only English!! Not only filename but also every-folder-path where file contains
If your file path is
C:\Users\Desktop\프로젝트\프로젝트.exp
You should change Korean(or any language) to English, Like below.
C:\Users\Desktop\project\project.exp
In detail
I just resolved what "Runtime Error 3055"
That's because "non-unicode folder location!"
Media lab and
Direct RT read only english..
If Folder-paths are not in English,
occurs "Runtime Error 3055, \ Not a valid file name."
If Folder-paths are in English, but only File-name is not in English,
occurs Medialab reads file-name as "??????.exp" and cannot read your file.
