Unable to log into the Board/League website on my main?

This is a smurf account.

On my main, I have a copy/paste password. I can log into the client just fine, so I know I am not getting hacked or anything, but for some reason, I am unable to log in on it here on the boards. It gives me an "incorrect summoner name or password" error, when I know for a fact this is not true. I have tried my login name, my summoner name, and all various different ways of getting in, but nothing works. So I cant even change my password. R.I.P
