Account no longer exists?

I created an account back in April, but attempting to log in to it now I can't get in at all.
The lost password feature also won't work, as it says it can't find my email in the database, although I still have the email for the creation of my account.
The account still seems to exist, as trying to register an account with the same username fails.Username is SamHPickeringAny help is appreciated.
Thanks

it exists but you registered it to a google throwaway email address so it probably no longer works.

I did? Damn I'm dumb.
Is there any way to get the email changed to my current email?

Can't since the account you're using now has it so I sent you a new password so you could log into it.

Thanks very much for your help and quick responses. :)
