Editing Theme has locked me out

I just tried to edit the Settings HTML via the WP control panel on the theme on my wordpress site and I got this message:

Parse error: syntax error, unexpected ‘)’ in /var/sites/s/sfgunofficial.co.uk/public_html/wp-content/themes/soundess/inc/settings.php on line 72

I then tried to edit it back to the original code that I had erased but got the same message. I decided before I tried to edit it that I would make a copy of the text of that page, so I deleted the text I had tried to edit and put the original back but still got that message. Now I can’t get into anything – the WP admin, my site or even the ftp site. I keep getting told I have the wrong password or that my username/email doesn’t exist.

I’m not sure where to go from here. I seem to be locked out of everything.

Any help greatly appreciated.
