Is it possible to unlink the home page and the register page in WPMU Nelo?

hi, i have the wpmu Nelo Theme with buddypress. The problem I have is that if I go to buddypress/page and I choose the register page is going to be name ” register” (default). Then I insert the register page in my menu, but instead of having the option of registering, they send me back to the home page, where I disabled the login option… Is it possible to get the ”normal” register page with this theme?
