Bug in Language File OR Function

[wizzy]

After changing the language to de_DE in setup everything works BUT as soon as you log out, you can not log in anymore. Resetting the pwd obivously works (you receive the new pwd as email) but again login with the new pwd does not work out.

I do no know wheter there is a BIG in the language file or in V2.0 handling other languages then en_US while logging in...
