App won't open – eDrawings Pro Review

I was able to view the sample drawings but when I went into iTunes and added my own the app no longer opens. I removed the files, reinstalled the app, even restored my iPad but the app just won't work. I want my money back, don't waste your money on this app. I'm ready to just switch to auto desk, at least their app works. New app update, now the app opens and works with the demo drawings but as soon as you add any of your files the app crashes immediately With the newest update, I can now open a couple of my simple parts, but anything complex and it crashes immediately. Still a 1 star review
