My solution to the CRPG update problem.

[IvoryDream]

1. I made sure to turn off the automatic updates in the properties of the game on steam.
2. I went to program files, clicked on steam, steamapps, and then common.
3. I right clicked on mount and blade warband and went to the properties.
4. I clicked on the previous versions tab and selected an option prior to the update.
5. I moved that version to my desktop, deleted the previous one and replaced it with the older version by dropping it in the common folder.

I don't know how far back your previous version is, but this worked for me.

I disabled this "previous version" stuff 
BECAUSE I NEVER HAD ENOUGH FREE SPACE

Since you now have the original 1.143 Steam exe could you please upload it for us?

Would be much appreciated.

It's on Vista and 7, and works only if you left the automatic backup stuff enabled.

Didn't the OP claim it works for him now?

Should be atleast in win7

He reverted the whole m&b - warband directory, not just the exe

Ah sorry, my reading comprehension is pants when I'm tired.

Now I understand how he fixed it, thanks.

Currently rolling back the directory to yesterday, thanks OP.

[Son Of Odin]

Yes and this method obviously works. Confirmed by SoO

[kono yaro!]

this worked 4 me. great thinking

[Sandersson Jankins]

Any chance of a workaround if I didn't do anything with the "automatic backup" stuff?

[SonicHog]

Great suggestion, worked for me. My only question is do you have to copy the previous version to your desktop and overwrite the existing one? Can't you simple restore the previous version? Anyways, it worked and that's all that matters. Thanks dude.

And if you have the steam version (yeah you pretty sure have it if you're reading this), remember to go to your games library and disable updates for warband after each time you stop playing. Steam is a bitch and puts it automatically back to auto updates after every time you've played warband. Yeah that's stupid. I don't know who the hell is the retard who made it like that, but just saying it can't be changed.
