Plugin Issue (bbPress install crashes site)

Each time I install bbpress (a recommended plugin) I get an Internal 500 error and everything breaks and quits working. I’ve tried installing the plugin manually as well as through the plugin library, and directly from the recommended plugin list provided with the BlackFyre theme. I want to be able to use the bbPress forums but as I said, it breaks everything when the plugin is activated. Please help http://wow-area52.com
