buddypress private pages

I have become the administrator for my website edmonton.refereerugby.com. I was beginning the process of getting my buddypress pages to only be accessible through members only using the buddypress private pages plugin. Install went fine and I commented out the code like the readme said now i have NO access to any pages on my site. NO access to the wordpress dashboard it appears to have completely obliterated my website. Please HELP!!! Is there a way to restore my website to a previous version or to at least remove this faulty plugin.
