Installation FAILED

I have a previous version of Slideshow CK installed on my WordPress-managed site on the GoDaddy hosting platform.
The license has apparently expired, so I paid for the latest version and downloaded the package.
When I go to install it, I get the error screen shown in the attached file.
Basically, it says this:

Unpacking the package…Installing the plugin…The package could not be installed. No valid plugins were found.Plugin installation failed. Go to Plugin Installer  
"No valid plugins were found"??? NOW what do I do? 
 

Hi

Slideshow CK installed on my WordPress

it's a long time that I have stopped to work for Wordpress (excepted for Template Creator CK)
so the package that you have downloaded is for Joomla

Please contact me by email with the info about the payment so that I can refund
