I don't know why this error happened there. Is it possible you ran some script as a shell user? That may have caused the permission problems.

If this problem pops up again, then there is another problem.

You say the it works now. Is the /d2 directory owned by a different user than the /d2/Scrble3x3.PNG directory and file?
