I can't add domain name because it's already in use by old forumotion account.

My new forum disallows adding my domain name because it's already in use by an older one which I have lost. I can't remember the webpage for my old forum and I cannot do a recovery because this forum doesn't have that option. I need to either A) Delete my old forum or B) Login to it and remove the domain name attached to it. Any Idea?
