BuddyPress.org

Hi! friends,
I am very new to Buddypress. I have problems in my installation. I installed wordpress 3.3 and installed Buddypress from the inbuilt plugin installer. I installed Custom community theme but when i try to create profile fields or groups on the site i got “There was an error saving group details, please try again.”. I have read somewhere that there is a table in mysql database for BP but looks like i don’t have one. I have 11 tables with wp_ table prefix but no BP table. I used softaculous to install WP. Is that true that there is no table for BP and have to manually install WP?

Thanks for any help.
