needs a fix

I am on WordPress 3.5.1 with SEO Friendly Images Personal 1.0.3. (no free version) The colorbox feature is working for me, but it has not revised alt and title tags for past posts as it said it would, even with clicking the update numerous times. That was the main reason for getting this. And I have submitted site maps to Google. Help! We’d like to recommend this to clients, but it is not working for us.
