I have msvcp60.dll in ~/.wine/windows/drive_c/system32, however the DirectoryPacker.mfx error still occurs. Using the terminal reveals that wine can't find Knytt Stories.exe (yes, I am typing it as "Knytt\ Stories.exe in the terminal). This instance of the game has been run on a Windows computer before and works fine. :| I have no idea what to do now.
