Crossfire Email

I just recently asked Z8 for the email linked to my account. It was an email i had long ago.
When i try to log in that email to change my current password & email, hotmail tells me that the email does not exist.

Z8 tells me that is the email linked to my account, so i don't know if this has to do with the new outlook thing going on..

Can someone help me please?

I'd probably take a screenshot of you trying to log into that email. If it does really show/tell that the email is no longer available, take a screen shot and send it to them and request that they change your email. Keep me updated about what you have done.
