You could try deleting the ibook from the iBooks app via the Edit button at the top right of the bookshelf, and then re-download it via the Purchased tab in the ibookstore in it.
If if re-downloads in German then try the 'report a problem' link from your purchase history : log into your account on your computer's iTunes via Store > View My Account (Store > View My Apple ID on iTunes 11) and you should then see a Purchase History section with a 'see all' link to the right of it ; click on that and you should see a list of your purchases ; find that ibook and use the 'Report a Problem' link and fill in details about the problem (iTunes support should reply within, I think, about 24 hours).
Some people have had a problem with the 'report a problem' link (it's been taking people to this site on a browser instead of showing a form in iTunes) - if it does that to you then try contacting iTunes support via this page : http://www.apple.com/support/itunes/contact/- click on Contact iTunes Store Support on the right-hand side of the page.
