History project video needs help

Hello! I am making a video as homework for my history project. Once I had finished it, I rendered it (obviously) and then tried to test it with Movies and TV (the program), windows media player and others. For all of them, nothing turns up. I need to email it to my teacher by Thursday (next week) and he does not have premiere elements to view it. Am I making a stupid error? Is the situation really hard to solve? Either way, I need to get this project to him as fast as possible. pls help!
