TOPIC: changing language in table-header?

Is there a possibility to change the header of the tables into german language? And also some phrases in the Registration forms? Thank you for support
A week later:
After a while of searching it seems to me that changing the language file ist not enough.
Thanks for help

First, make sure you have the latest version in place. If you have the German language setup, then you should have this file loaded on install:
/language/de-DE/de-DE.com_dtregister.ini

When the site is accessed in German, that file will be used unless there are errors in the file, in which case it will default to English. You can turn on debug to check that.

The German translation is not fully updated. We actually just got an update from the translator today... not 100%, but more than what you have. It's for the 1.5 version so we have to update the 1.7 version also... then add it to the next package update which will probably be available the beginning of this next week.

sounds good....
so I'm looking forward for the next update.
greetings,
