Problem to change email adress

I post this same text few days ago in newbies & introductions section. I got answer that I should ask same question in here.

So here it is: I have a problem. I tried to change the e-mail address. I managed to changed it but I can't read conversations anymore. I can't anymore see my account. I put the administrator an email but I have not been answered. I had no other choice than to make a new user account. Do anyone have similar problem?

I changed my email adress last Friday and problem is still on.
