Hello and welcome.
I just tried the links, and they still work for me. I have no way of editing them, as they are from a third-party website. If you are looking for the Screens 4 app, try these links:
Mac ($29.99 USD) or
iOS ($19.99 USD). For iOS, you can search Screens on the App Store for your iPhone/iPad.
If you were asking about other links in that article, let me know which ones aren't working for you.
Hope that helps,
C
