I moved domains and WP Smush Pro won't finish running

I installed WPMU and WP Smush Pro while operating a dev site at brennus.wpengine.com then started smushing. I moved the site over to http://www.manhattandigest.com before the smushing completed but it's not progressing. The old dev site is receiving the smushed images.

I tried uninstalling and reinstalling the plugin and WPMU on the new production site but to no avail. I'm erasing the development site now. I'm hoping that helps. Is there a fix for this?
