Hi Dev, My myetherwallet MNE genesis address has been hacked and the hacker has been taking out all of my MNE tokens, as well as all of my other tokens. As I can't change the private key to my MEW address, is there anything that we can do to make sure that he can't steal any more of my MNE?
Can I give you another MEW address and you change the MNE genesis mining to point towards my new address? If not, then this hacker will just keep stealing my coins every day

Let me guess: you feel victim to the MEW phishing attacks running rampant at the moment, right?
Anyway:
You address is dead. Nobody can change the fact that the attacker has access, including the dev.
No, I didn't fall victim to a phishing scam. I have been tracking back everything i've does, through looking at al the links i've accessed, through my history, checked my Mac for malware and spyware, but there's nothing that points towards being phished. I honestly don't have the first clue how i got hacked
