BuddyPress.org

Not clear whether you couldn’t access wp-admin right after you installed BuddyPress or not. If so, if you can’t access wp-admin, deactivate BuddyPress via FTP/cpanel/etc. and rename the buddypress folder in wp-content/plugins/ to something like buddypress-xx

As for GoDaddy hosting, I have read many heartaches of people trying to install BuddyPress and/or go Multisite there with shared hosting or better.
