Can manifold know why my serial number revoked

See the FAQ for "The serial number Status Page says my serial number has been revoked. Why would that be?" entry in the Install / Activate FAQ page.

Thank you Dimitri i saw the page before.

i checked my credit card statement i found out in 2018 i traded my serial number for upgrade.

The problem i checked my email and i did not find the new serial number.

so i am checking the entry in the https://manifold.net/tech/email_problems.shtml.

Other way is to gamble and purchase Key Recovery Service.

but can Key Recovery Service give me the new serial number if the email is correct?

but can Key Recovery Service give me the new serial number if the email is correct?

? Not sure what you mean by the above. If you have the correct email for your upgrade, you have the new serial number.

If you don't have your serial number email for the upgrade you got, time to use a key recovery service if you can still access the email address that you used.

Thank you Dimitri for the help.

I did find the new serial number in backup email.

And I reinstalled manifold-v9 latest release and happy to report it worked
