Lack of Metatags and SEO Plugin

Hi,

I got the rapid install of wp.mu... It seems to have ALL in One SEO Pack already installed.. but if I try to activate it, it says "this caused a fatal error" and then it disables it.

Perhaps I'm not supposed to use it this way when using a WPMU? How do I just get the metatag info filled out for the main blog? The site is http://www.projectblogs.com.

Thanks!
