Buddypress registration and sign in page not appearing

I am extremely new at all of this but getting the hang of it. I am in the process of creating a social networking type site. I am using BuddyPress (latest version) and the theme I am using is Custom Community. You have to be a member, that selection is checked also.

1. When I select sign up, my registration page does not appear with the profile fields. It’s a blank page. How to I get this to appear?

2. Login also does not appear. How to I get this to show up?

My site is active but a “under construction” page appears when you go to it. I have activated to theme without me being signed in and it still appears the same way. I get nothing! Please help!!! I need to get this figured out ASAP. Anyone that get give me precise step by step directions I would appreciate it because I haven’t been able to figure out by some of the posts here. Is there some other type of plug in I need? Or make a page in my cPanel admin? I am completely loston this one!

[No bumping, thank you. If it is that urgent, try hiring someone.]
