WPMU DEV Dashboard not recognizing Membership 2 Pro that is already installed

I have installed the WP Dashboard on the site, but when I go to update the Membership Plugin, it's not recognizing that I already have the plugin installed to let me simply update it. I am afraid that if I install it, it will loose all of the current settings. I don't have time to go through all of the settings again and set them up from scratch. What do I do?
