Change front end language of Fundraising Plugin

Dear WPMU Team,

Thank you for the great Fundraising Plugin!!

I will be using this plugin on a German website. Would you please be so kind to provide guidance as to how I may change the text on the front end (= the English text shown on the website) to German?

Kindly note that I used already your smart "Languages for WordPress" plugin to change the language settings to German on the back end.

I was doing a research on the WPMU community but was most not able to identify adequate search expressions. I thank you in advance for your help and send

kind regards
Cherie
