Crashes every single time a PDF file is sent to it...

I downloaded this APP yesterday and have tried about 6 times to send a PDF file to it and every single time it crashes. I just tried again and I told myself if it crashes one more time, Im done.
Sorry to the ones who made this app. All I can say is I have it a try.
