Smush PRO still nags, still "not pro"

Hello -- I installed WP Smush PRO (v.2.1.4) , as you can see here:

However, the plugin still says it's not PRO, still gives the nag to update, and still has limited features. See here:

I've cleared my cache. I've tried deleting, downloading again, and re-installing. I've made sure the old wp-smush plugin isn't there (in fact I never installed the "non pro" version on this particular website)
