Error Note when loading Szenario [Fixed]

[Merup]

Hello today i wanted to play the wave devense mode with my friends so i tested it before they came on and when i wanted to start it this appeared:Error while applying migration: Base Mod: 2014-01-28_Factorio_0.9.0.lua

__base__/migrations/2014-01-28_Factorio_0.9.0.lua:5: attempt to index field 'player' (a nil value) i dont know what that means so i tested the beta versions of the Game and in every single one of them the error appeared too

So i thank you for your feedback

Reinstall the game, you have some old files in your installation that should no longer exist.

I did reinstall it but this message appearedagain

Then go into your application directory, open data\base\migrations and delete the entire contents of the folder and reinstall again. If you are on Steam, you can also delete the files and then verify the integrity of the game files instead of reinstalling completely.
