WPMU DEV Dashboard pages giving an error.

I had WPMU dev dashboard on a site a few weeks ago. But I had to delete it to install new themes and do a site reset...but when I try to install it again it will activate but it doesn't show up in the plugins to let me control it.
No menu there and if I directly try to access it, I am getting this "Sorry, you are not allowed to access this page." Please help.
