download the latest version CB Paid Subscriptions

Good day,In 2019, I purchased CB Paid Subscriptions. However, I either didn't download or lost the plugin archive for CB Paid Subscriptions—I specifically need the plugin compatible with K2. I can renew my subscription and download the latest version, but I require an older version instead. There is a script conflict on the website that couldn't be resolved, so updating CB and CB Paid Subscriptions hasn't been possible. Therefore, I have frozen (cemented) the website in its current state.Could you please provide me with the plugin version:
CB Paid Subscriptions 4.3.0+build.2018.07.05.21.23.07.5cee7f443?Please help!

In our downloads, for each item, there is a drop-down where you can choose the version to download before pressing the Download button on its right:
www.joomlapolis.com/downloads

That old version is still available for download with a valid subscription (CB Paid Subscription or Developer membership).

I checked the list of CBSubs plugins and couldn't find any plugin compatible with K2. Please confirm whether such a plugin exists.

Version selection isn't visible to non-subscribes. As a subscriber you'll have a dropdown to select what version you want to download. This will let you download older releases compatible with different CB and Joomla versions. It will look like the following.
