BuddyPress.org

Hi,
I know that its not a new question but I have spent days on solving this issue with recommended solutions in the forums but I was not successful.
I try installing fresh WordPress on Wamp 3.8 (windows 7 and windows server 2012)
then I install BuddyPress 1.9.2 and add register page and activate page.
I add login widget of buddy press to sidebar.

when I go to website and click on my name or avatar to go to my profile page I see this 404 erorr:
Not Found
The requested URL /members/sara/ was not found on this server.
(same thing happens when I click on activities, members, groups)

Does it have a problem with Wamp? because Bitnami installation doesn’t have this problem.
