Footer.php code

Hi. I’m an idiot.
In my attempt to remove the Kriesi theme line from the copyright area, the entire code from the footer.php file has been deleted.
I followed the steps suggested. When I went to view the page, most image elements were gone and text had also disappeared. Went back to the footer.php file and all the lines were gone.
Is it possible to copy and paste the current updated footer.php code into the file and get everything back?

Thanks for anyones help.
