I may be a 'newbie' on the forums, but I've experienced this problem before. All it took for me to do was reinstall my FH and it worked fine. And no, it's not because you speak German in Cape, and you aren't banned. It would let you know if you were banned in-game. After you attempted to log in, it would say something like "You are banned for ___________" (in the blank, I believe that would be the time your ban lasts. I wouldn't know, since I haven't been banned.)
So maybe try reinstalling your FH. I had this problem due to some particle effects that I installed (no clue why it was the particles, I guess FH didn't like them.)
