Hello,
Thank you for your query and we are so sorry about the trouble this must have caused.
We can see that your purchased the Content AI Starter plan is already way past the refund period. Please note that Content AI plans differ from our Rank Math PRO subscription and you can use the premium version of Content AI without Rank Math PRO.
For initial troubleshooting steps, please install or update your Rank Math Plugin to the latest version: https://rankmath.com/changelog/
You can disconnect your account by navigating to WordPress Dashboard > Rank Math > Dashboard > Help and then simply disconnect the account by clicking on Disconnect Account.

Once you’ve disconnected your Rank Math account, you can connect it again in the same settings. In order to connect your correct account, click on Connect Now.

Once you click on Connect Now, please ensure that you’ve selected the correct account and then click on OK, Activate Now, as shown below.
Then head over to WordPress Dashboard → Rank Math → General Settings → Content AI and refresh the credits. Here’s a screenshot for reference:

Once done, please go back to using Content AI and it should work without any issues.
If it does not work, please share the affected URL/s so we can check on our end as well?
We really look forward to helping you. Thank you.
