[solved]Self Registration and FEU login don't work together

[nicola.yang]

i test the  {cms_module module=SelfRegistration group=somegroup}
to register a member and got it activated by mail.

but when I login this member by {cms_module module=FrontEndUsers form=login}
always get error : Login failed - Invalid username or password?

I trace the login check "function CheckPassword()" in FrontEndUsers.api.php . I found it chkeck the dabase table "module_feusers_users" and "module_feusers_groups".

But I also found that my new member data registered by Self Registran is stored in table "module_selfreg_users".
After I activated it, it still won't copy to the table "module_feusers_users"....

I think that's why I can't login after I done all the Self Registration part. Right?

Any suggestion?
