Problem with the nf_registration_mod module

Hi,

I'm using nf_registration_mod module to have two different registration forms for two different types of users. When I go with the pageroute to the form and after fill all fields ,the module only create a node but not the user. Some can help me? I was looking for solution but the solution that I find didnt go in my case.

On the register form, I dont have the username and e-mail fields ¿how can I put it on the form without have to create with CCK two field for that?

I'm using drupl 5.8
