Members Directory plugin disables widgets

Hi, I’m building a WordPress (regular, not multi-site) site with the following of your plugins: Membership Premium, Events +, E-Newsletter, Fundraising, Google Maps, Members Directory.

I have two questions:

1. The Members Directory plugin disables widgets. When I use the above combination of plugins, I cannot open any drop down (e.g. help & screen options drop downs at the top of each page), nor move any widget into the sidebar sections. Disabling Members Directory fixes this. Is there a solution to this?

2. Membership Premium interaction with Events +. I would like to have event information public but allow only signed-in members to RSVP for events. Is there a way of doing this?

Thanks in advance for your help!
