Login Package: no text for error "register.field_required"

Hi,

(Revo 2.0.0pl)

In my UpdateProfile page I use the UpdateProfile snippet of the Login package. I made one of the field ":required" but the error message I see is "register.field_required" even if the string is translated in the login/lexicon/en/register.inc.php file.

Any clue of how to get the normal "Field is required" message?

Thx

Thierry
