The "Support" section would probably be a better place than the "German corner" (since your question is not in German).
The good news, though, is that you have successfully activated your account, since you were able to post the question.
On a related note, sometimes when you get a link in an email, rather than clicking on it, you might have to select and copy the address and then paste it into your browser's address bar. This is because some addresses are not formated correctly by some email viewers (things like spaces and punctuation in web addresses can sometimes confuse email programs).
