language problem

hi there,

i use a worldpress multisite installation with the root blog in german and the english blog in the subdirectory /en/

but if someone registers/activates his account/request lost passwort on the german blog, some of the wordpress phrases are in english, eg:

*****
Kennwort vergessen
Please enter your username or email address. You will receive a link to create a new password via email.
Benutzername oder E-Mail:
Anmelden
Registrieren
*****

*****
Registrieren
Get your own mypage.com account in seconds
Username:
(Must be at least 4 characters, letters and numbers only.)
Email Address:
We send your registration email to this address. (Double-check your email address before continuing.)
Passwort
Passwort bestätigen
Passwortstärke
…
*****

I’m using other plugins as well like “jigoshop”, “theme my login” and “cimy user extra fields”, but even when deactivating these the problim still exists.

one of the urls is this:
http://www.imageproduct.com/login/?blog_id=1&action=register
blog 1 is the german one

this urls for blog_id=2 is comepletly in english, no problem there, and the strings are all in the offical german translation file…

has anyone a clue where i have to tweak to display these login/register/lost password stuff in german?

greets
alex
