I would just ftp it, but there is another way - if you have write access to the theme folder. Go to dashboard->Appearance->Editor if you see an 'update' button after the code, you have write access and can do this:
1) go to
http://wordpress.bytesforall.com/?p=81 and download a copy of the theme to your computer
2) unzip the theme
3) using a TEXT EDITOR (notepad will do in windoze) edit footer.php
4) do a select all and copy
5) go to the blog's backend dashboard->Appearance->Editor
6) on the right hand side you will see a list of 'Theme Files' - third one down should be 'Footer (footer.php)' - click on this
7) in the center of teh screen you will see the code, delete all this code
8) now do a paste in this area.
9) hit the 'update' button
