PDF2ID Plugin Purchase

I purchased the plugin PDF2ID on Adobe Exchange. I have a receipt that I received via email but I'm not seeing where it has been installed or I'm able to install it in Adobe Indesign. I purchased this plug-in on Friday morning. I sent multiple emails to Adobe and to the company that is managing the plug-in (Fastspring) on a Adobe exchange and I have received no response.

I just need help in getting the plug-in installed and indesign so I can use it.
