[TYPO3] How to config sr_feuser_register using German language?

[Andreas Balzer]

Hi! I downloaded sr_feuser_register and tried to get the German files 
through EM but it can't get them. I downloaded them manually and 
uploaded the zip into typo3conf/l10n/  It didn't help. Nothing happend.. 
What do I have to do? I set the T3 config setup template settings to 
German site-wide, so I think it has to do with the extension.. Anything 
what I can do?
