Account lost or reset.

I stopped playing nord invasion for a while, I changed the name in my M&B multiplayer profile but my account on the website works fine. I've tried to change my account name on the website to my old one but it wouldn't let me. I have the same name on the website as in my multiplayer account but when I get into a game I get an activation code and don't have any of the stuff I have on the website.
How can I fix this!?!
