I am sorry that you are having this problem.
I am not involved with the technical side of the forum at all.
I will try to get input from admin for you but maybe just try again every few days and see if it works.
I am sorry that I cannot be more helpful.
Actually, You can lodge a complaint, which admin will probably see, and then he will have your email address because I think you will have to include it
There is a link at the bottom of the page saying 'report a problem' try doing that.
I hope this is helpful. Get back to me with an update. I hope you can get your membership to activate.
