Can not verify the message. Are you sure you have not missed any character, may be any white-space?
Only posting the address is not gonna help I guess. You need the singed message from
Stake your Bitcoin address here topic. If you have not done it before then I am afraid your road is going to be very hard and the worse case will be losing your account for good. If you are the hacker then you can easily change the contents (including BTC address) of the above URLs. So only posting them actually do not prove that you are the real account owner.
