Have you set up bbPress in wp-admin > BuddyPress > Forums setup? Did you download and put bbPress in /wp-content/plugins/buddypress/bp-forums/ ?
Mohit Kumar, since I know you’re a regular around these parts, was this an upgrade from a previous bbPress installation? If so, is that installation external or internal? Were you previously using BuddyPress trunk, or stable release?
@Andy
I downloaded the zip file form the link that you gave in your blog +bbpress new version from bbpress website
i copied the bbpress into bpforums
