Password change - how?

[info@.....com]

I am new to this forum and can not change my password.
In User Control Panel, Profile tab, Edit account settings whenever I click submit I get

'The current password you entered is incorrect.'

and I am sure it is not!

Hello, please use this link:

the email address is also a username in all of our site. The joomla username/email is used at the forum as well. If you had any issue with this, let us know and i can update the password manually for you.

Best Regards,
