Dreamweaver not responding and very slow

when I was using dreamweaver, I was working on navigation coding and it quit unexpectedly. I reopened it and it ask me about unsaved files or data was still there and it ask me to either "recover" or "discard". I can't click on either of them because, it's loading very slow and does not respond and I can't do anything else on dreamweaver. I try turning off the laptop, uninstall and reinstall, nothing had work. This is a MacBook I'm using
