achievement data lost and our configuration reset.

[remonn00]

Everytime I open the game two pop-ups appear:

Notice:
Your configuration has been reset.

And

Data Error:
Failed to load local achievement data. Local achievements might be lost.

I have already re-installed the game but this doesn't solve my problem. Does anyone have/had the same problem? And does someone know how to fix this problem?

You should be able to solve it by deleting the %appdata%\Factorio folder. Make a backup of your saves and mods that are inside first if you don't want to lose them.

It worked! Thank you!
