Affiliates WooCommerce integration plugin is not downloadable

Hi,

We are setting up the Affiliates Enterprise plugin we purchased on our website.

We need WooCommerce integration.

In the integration settings, it first asked me to install itthink​ plugin so I clicked install​ button and it installed the plugin successfully.
After that it asked me to install Affiliate Woocommerce​ plugin so I clicked install​ button but it sayd Installation package not available​.
It doesn’t allow me to use Affiliate WooCommerce Light​ version so I am trying to figure out how I can download the advanced version.

I looked at the article https://www.itthinx.com/plugins/affiliates-woocommerce/ here but it doesn’t tell me how I can download it.
I logged into our account and checked the list of downloadable plugins but it’s not listed there either.
Can you please let me know where I can get this plugin?

I attached screenshots for your reference.

Thank you for your help in advance!

Additional info:

Installing the plugin is not working both on local setup and staging environment.
