This is not Adobe, and Adobe is the only one to resolve Activation and Serial Number issues. Typically you contact Adobe via its Adobe Chat.
These days it is often difficult to contact Adobe Chat because it is undergoing updating. So, sometimes you click on the link to it and get only Ask the Community. You want Chat Panel and not Ask the Community in order to get to Adobe Chat.
The following link for Adobe Chat is active at this moment. I just tried it.
It has been pre-set by me for
Premiere Elements
Adobe ID, Signing In
Adobe ID, Sign In, Account Help
Chat Panel
If the web page set does not hold, then use the above titles to navigate to the Chat Panel.
Please let us know the outcome.
Thank you.
