php script error

I am using a free script from hotscripts for multiple file uploads....I uploaded all files to server and tried it, and this is the error I get:

Warning: move_uploaded_file(naturaltalent.cc/xml2/files//signed.jpg): failed to open stream: No such file or directory in /hsphere/local/home/naturalt/naturaltalent.cc/xml2/uploader.php on line 116

Warning: move_uploaded_file(): Unable to move '/tmp/phpM2CkCe' to 'naturaltalent.cc/xml2/files//signed.jpg' in /hsphere/local/home/naturalt/naturaltalent.cc/xml2/uploader.php on line 116

here is the php code from the script:
