Hi Beau,
We have just now released a fix to this (v1.99g). Sorry for it taking for so long, we had some key people on vacation + working their day jobs on an extended spree, thus some unexpected delay.
I hope it solves your problem, at least worked for me now.
If you run into not being able to start Batclient, clear your Java cache (Control Panel -> Java -> ..) and reload client from the web
