Thanks for PMing the FTP info.
Just in case anyone else would like to do something similar, I'll post the solution here and lock the thread:
I changed line 148 of "s5_admin/s5_fw.php" (the last line of "s5_inject_date()") from
return $return;
to
if(!is_singular()){return $return;}else{return '';}
What this does is check to see if the current "page" being loaded only has a single post or page worth of content, and if it does, instead of injecting the date, it erases the area where the date would go.
