jim618 was the developer behind Multibit but once he sold it to KeepKey things are not as used to be. I suggest opening an issue on their
GitHub Repo and waiting for a response but I doubt you will get a fast one , or you could explain your situation to the community and hopefully we could help because since Multibit HD is decentralized , I don't think there is something developers could do that the community can't unless It's too technical.
