Multi site--Can't access dashboards or new sites

I have a membership site and I have only used the multi site feature in the past for testing.

Now I need to create a few new sites. After creation I am unable to access the dashboard or the new site.

When I try to access the new site I get this message:

Apache is functioning normally

When I try to access the dashboard I get this message:

404 Not Found
The server can not find the requested page:

members.sisterhoodofsupport.com/wp-admin/ (port 80)
Please forward this error screen to members.sisterhoodofsupport.com's WebMaster.

Apache Server at members.sisterhoodofsupport.com Port 80

I am using wordpress 3.5.2 with membership premium 3.4.4.1 and buddypress 1.7.2 plugins.

The only dashboards I can access are network admin and my main site admin. The only site I can access is the main site (sisterhoodofsupport.com).

I don't know exactly when this happened as I have not tried to access this feature in quite a while.

Any help will be greatly appreciated.

Thanks,

JoAnn
