Registration problem

I signed up for a WordPress account yesterday, but the registration email shows up as blank in my email program. I’ve checked it in webmail as well, and it says the email is “invalid multipart content” with nothing to display.

So now I can’t login to use the blog name I wanted, and I can’t sign up for another account using a different email address, as it says my blog name is reserved. Is there any way to have the registration confirmation email resent?
