Installed plugin, but TrustActivity doesn’t show up on my left dashboard menu

I’d like to try this plugin but it’s not working. I installed it and activated it, but everytime I click the “TrustActivity is not configured! Click here” alert, the page loads but goes nowhere. The TrustActivity link that should be in the left dashboard menu isn’t there either. Even though this plugin was updated 7 days ago, it does say “Warning: This plugin has not been tested with your current version of WordPress.”
