WPMU DEV Dashboard Plugin

Hello,
I have been troubleshooting my website for the past week and have come to the conclusion that the WPMU DEV Dashboard plugin has been giving me a 500 error message. I was not able to log in until I deactivated all my plugins through my FTP files. Once going through each every time I would activate the WPMU DEV Dashboard plugin it would give me the same error. I would like to have the plugin installed but if it keeps giving me an error message I will unfortunately be unable to use it. Is there something that I need to do to fix it?
