Transfering my Blog ?

I may need to start a new blog , unless someone more experienced can help me.
A while ago someone stole my email address. ( the one this blog is registered under )
I changed the pass word etc and started a new email account. However, today I got an email from the old account ( I have emails forwarded to me ) that someone is using that account still.
So im not comfortable having it . I want to delete it . The problem is , i cant figure out how to get my new email address attached to my blog.
SO I may need to copy all my info and start a new blog .
IF I do i will let everyone know i hope everyone follows me over .
If anyone know's a better way to do this please let me know
