not possible to be pro

I am having the same problem as Alex. I want to go pro but the link is broken.

Same here the plugin seems dead

I got the business package with 5 licenses. I’m still using 3 with WP 4.3 – They are working. But now there is no possibility to upgrade lightbox 2 (simple) on https://www.architekturfotos.net to the pro version.

Hope the developers will show a reaction!
