If you’re getting an error message reading “Error User File is Wrong Size" or "Invalid File Version” or "File Too Short" when trying to play the game Plants Vs Zombies, this means that the save data for the game (where your game progress is stored) has become corrupted.

This prevents the game from launching and will give you these error messages.



How do I resolve this?

To fix this, you will need to delete the corrupted save data files. While this means you will be deleting your game progress, you will be able to start fresh using your new experience to get even better scores!



Where are the save data files?

This will vary depending on the Windows Operating System you are running.

Windows XP C:\Program Files\PopCap Games\Plants vs. Zombies\userdata

Vista, 7, 8, 8.1 and 10 C:\ProgramData\PopCap Games\PlantsvsZombies\userdata

Once you have located the folder, you will want to RIGHT click on it and then select DELETE. Now you can RIGHT click on the Recycle Bin, and select “EMPTY RECYCLE BIN”. With those steps done, you just need to reboot your computer.

That’s it! Now you shouldn't have any trouble playing the game.
