She has already changed the email, and I have activated her account because she didn't receive the email confirmation.
Did you check the spam folder of your email as well?
If there is nothing, then there might be a problem that your email provider blocks emails from GamersHood Forums.
This is true for all AOL customers for example, against which we can't do anything unfortunately.
I'm not sure if your email provider has the same issue.
In that case you'll need to change your email again
