very frustrating daily challenge on taptiles not working in May

i am uninstalled and am trying to reinstall, and even that is not working in a timely manner.

My Taptiles Daily Challenge has not worked a;; day, what should I do ?

Just a question. Why can I play Taptiles daily challenges, but not Mahjong or Solitaire daily challenges?

I have the same problem on a windwos 8 laptop. After the updates of Mahjongg, Minesweeper, Taptiles and Solitaire, the system still logs me in (it shows my avatar and even my awards), but whenever I start a daily challenge the error "DC files are not available".
This is very frustrating.

I can still open Taptiles (the old version which I prefer to the Microsoft Taptiles 10 version) but when I click on Daily Challenges, I get the message 'There was a problem launching Daily Challenge data., Please refer to error code 002000. I tried opening Taptiles from the Microsoft Store, My Library, Owned as you suggested but the same happens. It opens OK but then I get the same message when I click on Daily Challenges. I notice that Taptiles is no longer in the Microsoft Store - only the newer Taptiles 10 version. Does this mean that Microsoft have discontinued the old version of Taptiles? I remember that some time back Microsoft discontinued the old version of Soduko which I also preferred to the new version.
