[PC] Plants vz Zombies - "We could not activate on this computer"

Based on the information provided, it seems that you're encountering an error message stating that you haven't activated Plants vs. Zombies on Origin, even though you've been able to play it before. Here are a few suggestions to help resolve this issue:

• Verify your game's activation status: Double-check the activation status of Plants vs. Zombies in your Origin game library. Ensure that the game is correctly registered and activated under your account. If it appears as activated, try deactivating and then reactivating it to refresh the activation status.
• Restart Origin and your computer: Close the Origin client completely and restart it. Additionally, reboot your computer to ensure that any temporary issues are cleared and the client starts fresh.
• Repair the game files: In your Origin library, right-click on Plants vs. Zombies and select "Repair Game." This option will scan the game files for any errors or missing components and attempt to fix them.
• Clear Origin cache: Clearing the Origin cache can help resolve various issues. To do this, go to the "Application Settings" in Origin and select "Advanced." Click on "Clear Cache" and confirm the action. Then restart Origin and try launching the game again.
• Update Origin: Make sure that you have the latest version of Origin installed. Check for updates in the Origin client and install any available updates.

Contact Origin support: If the issue persists after trying the above steps, it's recommended to reach out to Origin support directly. They have access to specific account and activation information and can provide more personalized assistance to resolve the problem.

So I own the standard edition of Plants Vs. Zombies. Installed it today after not having it installed for a long time. Now it's giving me an error message saying it can't activate Plants Vs. Zombies game of the year edition.

That's not what I own, or what I am trying to play. It's asking me for a product key. I tried to enter the product key for my edition of the game, but I can't even get to that part. When I click the "Enter product key" button, it says "An error has occurred. We've noticed your computer is offline." and tells me I need to be online to activate my product. Clearly I am not offline. Neither is my EA app.

I've tried repairing the game. Uninstalling/Reinstalling. Turning EA app offline and back online again. Also turned off EA app completely and relaunched. None of these have worked.

What can I do to resolve the issue?

I own Plants vs Zombies PC game through Origin, and I am supposed to access it nowadays through the EA App. 

The problem is, the game will not launch. 

It keeps giving me an error message. 

cause they did something wrong. with Origin it was working, now with EA app it doesn't. all of us have same problem. assistance won't help, don't waste your time friend. they aren't giving refunds either

the next steps i'm gonna list they asked me to do them 6 times in 3 weeks of emailing and Live chatting
i had to show them i own the game and the pay record from 2017, show them game doesn't work, deleted all process from Local disk C, unistalling and reinstalling EA APP and all games, run game and EA APP as admin.
nothing worked

having the same issue, any solution so far?
