Whoops! I tried to install a theme and…

I attempted to install buddypress community to the root site install of my multisite, buddypress project and received this message:

Fatal error: Cannot redeclare bp_dtheme_register_actions() (previously declared in /home/content/35/9282035/html/wp-content/themes/bp-community/_inc/ajax.php:30) in /home/content/35/9282035/html/wp-content/plugins/buddypress/bp-themes/bp-default/_inc/ajax.php on line 77

Of course, I cannot gain access to the page again or the admin login. I can still go through my hosting account to work on it from that level. Do I need to just scratch what I have and start over? I was having problems with installing plugins and themes because I had setup a site prior to joining WPMUDev, and had installed themes and plugins that seems to have caused some problems with changing themes and removing plugins on the local site level.

I’m still new at this, so, I could easily be missing something.
