We just released Traffic Getting SEO Plugin version 2.1.1 beta a couple of days ago.
This update fixes errors reported by some users with WordPress 3.0 incompatibility. If you are having trouble installing TGSP on your WordPress 3.0 blog, we recommend installing this update.
When 2.1.1 is officially released, you will be notified as usual in your WordPress Admin Panel.
To download, visit the Traffic Getting SEO page in our Traffic Quick Start module.
