[TYPO3] Ext: Front end user registration

[Miguel Angel Calleja Lázaro]

Hi! Im trying to configure this extension. Im following the steps:
http://typo3.org/documentation/document-library/sr_feuser_register/Configuration-27/
1- Ive installed Static Info Library extension, New Login Box 
(newloginbox), KB MD5 FE Password (kb_md5fepw) and FE, BE Library 
(fh_library).
2- Ive added 'FE User Registration CSS-styled' in TypoScript template.
3-Ive created a System Folder page that will contain the records of 
Frontend users created by the extension. I Set the TS template constant 
*pid* to the page id of this folder. Under the System Folder, create two 
Frontend User Groups. Set  the TS template constant 
*userGroupUponRegistration* to the uid of the first group and constant 
*userGroupAfterConfirmation* to the uid of the second group. The second 
group gives access to the pages targeted at the registered front end 
users, while the first group does not. Pid=65
4-Ive created a page, setting the Page "General Storage Storage" to the 
System Folder that will contain the front end user records created by 
the extension. I insert the New Login Box on the page. Then, on the same 
page, after the New Login Box, I insert the Front End User Registration 
extension, leaving the CODE empty,  setting the Starting Point to the 
System Folder that will contain the Frontend user records created. I Set 
the TS template constant *loginPID* to the page id of this page. Pid=66
5- Ive created a second page under the previous one. I Insert the Front 
End User Registration extension, setting the CODE to *CREATE*, and the 
Starting Point to the System Folder that will contain the Frontend user 
records. I set the TS template constant *registerPID* to the page id of 
this page. Pid=67
6- Ive created a third page, also under the first one.I Insert the Front 
End User Registration extension, setting the CODE to *EDIT*, and the 
Starting Point to the System Folder that will contain the front end user 
records. I Set the TS template constant *editPID *to the page id of this 
page. Pid=68
7- Ive created a fourth page, also under the first one. I insert the 
Front End User Registration extension, leaving the CODE empty and 
setting the Starting Point to the System Folder that will contain the 
front end user records.  I Set the TS template constant *confirmPID *to 
the page id of this page. Pid=69

Concluding my typoscript template, in constants:
pid=65
userGroupUponRegistration=1
userGroupAfterConfirmation=2
loginPID=66
registerPID=67
editPID=68
confirmPID=69

Ive done all this. I try to see if it works... i create a user in 
register form, mails confirmation works correctly, I confirm this user, 
I look in database and i see that this user has been created, but when 
Im going
to login with this username and password an error appears me saying me 
that user and passwords are incorrects. I continue proving and i click 
in "Have you forgotten your password?", i enter email and
the notification that i obtain is that database cant find username with 
this email, all dates its fine,
 what is I doing wrong to login? Is my configuration wrong?
