Error Message about corrupted file. Won't open on multiple devices. Why?

Hello,

I have an ebook document I saved using Document Cloud. I use Adobe Reader on my Samsung Tab 4. I have hilighted and made notes so I would like to figure out a way to recover my saved file. I was just reading this book a few hours ago. I tried to open it and my device suddenly tried to read it from the cloud. It took a while, but once it was loaded, I got this error. I have no idea what happened or why. I didn't do anything but bookmark a few pages. Please, someone, help me...
