BuddyPress.org

Hello I´m new user here!
So I had some problems with buddypress 1.5.2. instalation on wordpress 3.3. Once I had allready installed the plug-in i had found some problems displaying my site (www.mundocrudo.com) so I decided to uninstal buddypress on the server side by FTP. Once I remove the buddypress folder from plugings my displaying problems where finish but once i reinstall buddypress i can´t see my website anymore.

Somebody knows how to remove buddypress by the server side, not just the buddypress folder, what other files i have to touch?

Thank you very much, god bless you!
