VMTranslator passes on own computer, but fails on grader

[A_Random_Person]

When I run my VMTranslator on my personal computer, it passes all the test. However, when I submit it, it fails unexpectedly. Here is what the grader spat at me:
*(-15) - The submitted VMTranslator failed to translate FibonacciElement
*(-15) - The submitted VMTranslator failed to translate NestedCall
*(-15) - The submitted VMTranslator failed to translate StaticsTest

The output file should be VMDirectoryName/VMDirectoryName.asm, but on the grader the VMDirectoryName.asm turns into /.asm. Why is this happening, and how do I fix it? I've already tried running the VMTranslator on another computer, but it still works.

A likely candidate is that one of you is running on a Windows machine and the other is running on a Linux machine (or possibly a Mac). Are you using the operating-system agnostic file and directory utilities, particularly with regard to path separators?

Another possibility is that there is a disconnect on what directory you each are running the program from.

I would recommend having a discussion with the grader to home in on the exact situation that results in the problem.
