I am having the same problem. After trying to use the green renewal button for a week (goes to page not found), I contacted Malwarebytes on 12/19/17 and got ticket 2170381; nothing heard back. Today, my subscription expires. Sure could use some HELP. I do hope your problem was successfully resolved. I know your frustration. Odd, I want to give them money and they don't seem to want to receive it.
