BuddyPress.org

I just installed buddypress a few days ago and my User Groups, Members, Activate, Register pages are not working.
I went through the installation wizard, made new pages for Activity Streams, User Groups, Members, Activate, Register and associated them to buddypress components.
But if I view those pages, they are just newly created empty pages.
I set buddypress activity template for Activity Streams page, so Activity Streams page is working but other pages are still empty and I don’t see templates for other pages.

I’m not sure if this is related to the issue, but I had a problem with setting up permalink before.
I had to include index.php in the permalink and it is working now.
Also, what I am developing is an internal intranet site.

Anyway, I have no clue what to do at the moment.
Any help would be greatly appreciated!
