Hi, you have created many posts about your problem. It is really not necessary, we respond quickly even if you just post once. 🙂
As explained in the other threads, you will need to download Spine from your Spine license page and reinstall, then it will work again. It is not sufficient to reinstall with a Spine installer that you downloaded in the past.
If you can't find your Spine license page, please use this page:
Spine: License Recovery
Sorry for the trouble!
