You know, I don't really see how code can be plagiarized (outside of direct copy-pasting, I guess) because code is designed to be re-usable, and it's not like you can copyright code (can you?). Graphics, music, story, all that can be plagiarized but I do not see code as being plagiarizable.
edit: "What the heck...I recognize this for loop... This is MY for loop! This bastard stole my freaking for loop!'
edit2: Although I will agree that code as an entire project can be plagiarizable, but if someone opened up your project because they wanted to see how to make your rad CMS or whatever, I don't believe that's plagiarizing them.
It really depends, as there have been a few cases where people have opened projects, stripped out everything but the custom systems and then put their own game on top - and this is probably the circumstance that most people are trying to prevent. This is why there will never be a non-locked build of FF72DR released publically. Hell I couldn't care less about people seeing the code, or using some of the algorithms, but what I don't want is to inspire a series of sub par FF7 spin offs just because my project provides all the custom systems and resources needed to do so.
With regards to the OP's question; we can't really help you unless you tell us what error you're getting. Is it a missing file error? Is it a Molebox related error? What does it actually say or what actually happens? It just sounds to me like you didn't include any of the resources.
