bbPress.org

I just instaled bbpress forum and i’m having problems with new user registration. I use iblogpro forum with iblogpro wordpress, i deep integrated wordpress and bbpress but i don’t share user between wp and bb ’cause i don’t alow any kind on coments on site or wp registration, i have separate databases for wp and bb, and everything works fine, but when i try to register like a new user i allways get “Email is required” but every time I input correct mail example name@gmail.com?
