BuddyPress.org

I installed BuddyPress but ran into some problems, so I deactivated it, deleted the files and dropped the database tables. I then re-installed it, but found that something must have remained because when I re-installed it and activated it, it didn’t offer to run the set-up, and the settings from before remained.

If I deactivated it, deleted it, and removed the database tables, what is left that I still need to remove to reset everything? Thanks.
