Can't Find Visitor Log

Today I upgraded to version 1.4 but I cannot find the visitor log. Or anything regarding live visitor stats. Isn’t it supposed to be under Visitors > Visitor Log? I don’t have that option. Does it need to be installed or enabled some how?

And yes, I have set my date range to include today. Including tried to view results for only today.

Nevermind. Apparently you have to activate the ‘Live’ plugin. It really should say so in the Visitor Log documentation.
