Some of the activation links have been wonky for people. For some, all you need is to give the server a bit of time to works its magic, and within a day or so, it sorts itself out. I've checked your account, and it appears to have been activated, so you should be good, for the most part. If you're still experiencing issues with it, though, feel free to PM a staff member so that he/she can check in and see if something else went wrong. c:
