Changing confirmed email.

I just cracked an account but the problem that it has a confirmed email I tried to use the password that he used in the account in his gmail account but it didn't work so I need your help if any one have a way to change it.

Tough luck for you, unless you manage to guess the gmail password, the account is not worth keeping.

Buy the account an AC or membership package.
Use the trans id to recover the account (I know you already have access to it, but this will make the email unconfirmed).
Attempt to change the email now.

Be sure to report back and let us know how it went.

Source: Some nub used a trans id on my account twice and both times it made my previously confirmed email turn unconfirmed.
