when attempting to change my email address on this Imperial Forum (option at the top right of the profile page ) it asks you to confirm your password, when i enter my password to login on the main site imperialconflict.com is says the password is incorrect

same goes for trying to change the password 'The old password you entered was incorrect.'

maybe its a bug? 

the two are linked because your automatically logged in on the forums when you logon the site but they must have different passwords ?
