WPMU DEV dashboard crashes test site

Hi,

I signed up yesterday!

Attempting to start using some plugins. I have a test site running on MAMP. I downloaded the WPMU DEV dashboard plugin, copied it into my plugins directory. I then activated it within the dashboard but I then just get a white screen, I can't go back to the dashboad after this also.

If I remove the WPMU DEV dashboard plugin the site operates as expected.

I have other plugins installed, including:

AddThis Social Bookmarking Widget
All in One SEO Pack
BackupBuddy
Google XML Sitemaps

Do I need to deactivate these plugins?

Thanks
