Automatically I was logged in with my old password, then tried to login with my correct one, but it did not permit me to do so. After that, I forgot my password, and I think my email has been closed down. So I can't retrieve it. Any help?

Since you're logged into the account why don't you just change the email address & password while you're in it? :/

/me points at UserCP

I need to enter my current password to change into a new one.

It's saved in your browser, look at the saved password list for it.

Where is it exactly?

Depends on the browser you're using

I looked but it wasn't there. Only other sites.

It'll be there somewhere, otherwise it wouldn't have been able to automatically log you in.

If you're able to login ingame then you could poke the file that contains your user/password with notepad.

Ok.

If you can't find it just tell us what browser you're using.
