I've got the Toribash 4.3 and it has some "autoupdate.txt" file, but it only works when offline, and crashes the game.

So I deleted it
//Had some <br><br><br><br><br><br><br><br><br> thing, deleting it made the game work offline

I was wondering how is it normally updated, do I have to download the setup again? If so, wont it delete all the replays and stuff?

Thanks for helping me.
