What I have uploaded to my site is missing the doksoft_uploader/config.js file and I can't find the original download link. Should I get a refund and purchase it again or what?

I am having trouble installing the CKEditor Quick Image Upload+ plugin. The icon has been added to the CKEditor toolbar and I can open the dialogue box and navigate to a file ok. But when I try to upload, the red circle is replaced with a yellow warning triangle and the file does not upload.
The installation guide is not 100% clear on where to amend the upload path in the config.php file, and I may have the path to the actual uploader wrong in my config.js file also.
For example, exactly where in these lines do I add my own upload file paths in the config.php file?
code]$config['BaseUrl'] = preg_replace('/(uploader\.php.*)/', 'userfiles/', $_SERVER['PHP_SELF']);[/code]
and
code]$config['BaseDir'] = dirname(__FILE__).'/userfiles/';[/code]
and does the path to the php uploader in the config.js file need to be absolute or can it be relative?:
EG
code]config.doksoft_uploader_url = '/admin/ckeditorfull/plugins/doksoft_uploader/uploader.php';[/code]
or
code]config.doksoft_uploader_url = 'plugins/doksoft_uploader/uploader.php';[/code]
neither of the above work.
File permissions are ok, I think I am just struggling with the file paths...

I would like to know, if there is a possibility to upload images into exactly specified directory in CKFinder whilst I am uploading it on my CKEditor website preview. Now images are uploaded in root directory "Images" in CKFinder. I would like to specify a unique directory for each upload.
