Filmstro extension

Hi there. Is anyone familiar with the Filmstro Premiere extension? It was on Adobe Exchange but has been removed since Filmstro has migrated away from their powerful desktop software to a nauseatingly cluncky and feature-poor web app. I came across Filmstro several years ago on YouTube and always said "one day." I finally subscribed to it only to come across this dreadful news afterwards. I was able to find a download link to the standalone software but it was the very first version and isn't very polished. I would really love the Premiere version, but have scoured the web and not found a single download link. I was wondering if anyone might have an installer that they could share. Thanks.
