I'm sharing the solution of this issue which you can keep using the Starter Plan with no problem even It's not shown on the website due to an issue they're fixing. This is confirmed with the agents I contacted. The only thing that you have to do is open the application located in the folder of documents, do not open it through Creative Cloud because it will aks you to pay and in case the app says there's an update available in the future you can update without problem in the section of updates of CC.
You can download the setup, if it ask you to pay while you're installing just skip that step, if it doesn't work use the trial option to continue the installation and cancel the susbcription immediately (after installing). Once you do it you implement the solution that's written in the first paragraph. For evidence you can these pictures which on CC it shows try or buy even I still have the Starter Plan.
Hope this helps.
