Was tolerable until error

I purchased this to complete a collage story for school and it did just enough for what i needed, however when i went to save the final product ( after 4 hours of making it, mainly just working around the shortcomings.) I was told it was damaged and that i needed to redownload it. Then crashed, taking out all that work in about 30 seconds. I was livid.
