Sorry... I have to say that modx strikes me as one of those CMS that was up and coming, the next big thing, but it just never really came up and got big.
I feel like there's a consolidation in the open source CMS market as people have experiences like yours and end up settling into Wordpress, Drupal, Joomla, Xoops, and the like and it's getting harder and harder for people, once or twice burned, to jump on a new CMS.
I realize that does you no good, but I expect that's what you're seeing here - a small user base that is getting smaller.
I'm most familiar with Drupal, then Wordpress and have seen that as more and more enterprise-scale installs there are out there, the more professionalized the release cycle gets in terms of what constitutes beta/release candidate/release, having unit testing, etc etc.
sorry to hear about your woes!
