I can see the problem immediately - somehow, the replies on your forum aren't in ascending ID order.
For example, in this thread: http://localsportsreport.com/gojhl/forums/topic/how-big-was-the-falcons-error-now/#post-10321
The reply IDs are #10321, #10320, #10319, #10316... then back up to #10318. There's no consistency in how they're ordered - which I've never seen before in bbPress. The plugin relies on the last post in a topic having the highest ID, which isn't something I'm able to change right now.
Unfortunately this means that the plugin won't work on your forum as-is. If you can find out what's causing the strange reply ID behaviour (my only guess right now would be if your theme is causing it?) and change that, then the plugin should work. Alternately, if you're comfortable with PHP you could try to implement a solution yourself, but for now at least I won't be changing the base plugin functionality.
Sorry I couldn't be of more help, and good luck!
