Can't receive email and I have forgotten my password

Hi.
I just bought a Theme Forest theme for my wordpress. I have to confirm my email address so I can download it, but I just dont receive the email. I cant receive any email from theme forest and envato (I just made a test, sending an email from another email account and it went right.)
But I cant change my email addres (so I can receive in another email), because I need to confirm my password, witch I have lost. And I cant change my password because I dont receive any email in my mail box.

I just want to be able to download my theme, how can I do this?
ps: sorry for my bad english!
