and/or contact the administrators?

I guess there's no official hashnest support here and it's bad that a lot of people haven't managed to solve their problem.
A little hint, it looks like hashnet has been acquired by bitmain. If this acquisition is still valid, maybe you can contact bitmain support instead.
