Love this app but quits constantly now

I use this app to scan my law school readings and then copy and paste the techincal material into my notes instead of having to retype everything. It’s been great for at least a year, as long as I’ve been using it, but in the last two or so months it keeps quitting on me everytime something has finished OCRing and then I lose the work. It’s a gamble everytime. I updated to Sierra hoping this would solve the problem, but nope. If they can fix this, it’ll be a five star app again. For now, it’s not useable.
