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

I deinstalled Origin and installed the EA-App.

But the problem still exists: When I am told to activate the game and put in username and PW, the system tells me they are wrong (but I use them to log on to the app the the forum).

If I choose "create new account" I am told, I was offline, however.

Same if I choose to put in a serial number

This is still being looked into with different teams as older titles are getting similar errors:

As of now, below are the steps that should resolve it but may not be for everyone! The idea is to get rid of all files relating to the game from the PC, so the download provides a fresh install with no older files within the registry or documents.

Delete EA License Files:

• Make sure the EA app is closed.
• Press the Windows key and "R" at the same time.
• Type or copy and paste "%ProgramData%\Electronic Arts\EA Services" (without the quotes) into the new Window > ENTER
• Enable View Hidden Files and Folders
• Delete all files in the "License" folder.

Please clear your temp files:

• Press the Windows key and "R" at the same time
• Into the new window, type or copy & paste: "%temp%" (Without the quotes.) > hit "ENTER"
• Your Windows Explorer should have brought you to the "C:\Users\>your user name<\AppData\Local\Temp" folder. > Delete all files and folders in it.
• (If some files or folders can't be deleted, reboot and try again.)
