Is there anyway to convert mathcad prime 2.0 to mathcad 15?

I unfortunately uncovered some of the pitfalls of the Mathcad Prime 2.0 and I am now trying to revert back to Mathcad 15. Unfortunately, I discovered the problems with prime after I completed a lot of work. I was thinking that the formatting issues surely were just because of my ignorance of Prime. Shame on me I guess. Does anyone know of way to convert mathcad prime files back to mathcad 15 files?
