DayZ “Files are not signed by a key accepted by this server” fixes

The error in question is this:

Here’s a quick reference guide since I haven’t found any definite answers on the internet. These may or may not work, so try them at your own risk:

1 - Close everything (Arma 2, DayZ Commander, Steam, etc) and re-run everything as administrator if not doing so already. Try to open DayZ again.

2 - Test other servers and see if the problem exists with the server itself or with you. If it doesn’t happen on other servers, try on the original server again. It might be a server issue and it will occasionally fix itself.

3 - Go to C:\Program Files\Steam\steamapps\common\Arma 2 Operation Arrowhead (Or whererever the steam files are located) and delete the “@DayZ” folder. Reinstall it using DayZ Commander or other program. Try to open DayZ again.

4 - Open the @DayZ folder and open the Addons folder. Locate the “bisign” files. If they are not in there (or the .pbo files are not there), delete the @DayZ folder entirely and redownload it.

5 - Run Arma and Arma 2 until the menu screen. Then try to open DayZ again.

6 - Open Arma 2 (the base game) and at the main menu, open “Expansions”. Enable DayZ (and other add-ons). Then try to open Dayz again.

7 - Bad CD keys give a different error than the error(s) above. Do not be fooled into buying new CD/game keys.

8 - You do not have to reinstall the entire game, as the errors are with the @DayZ file, not Arma/CO games.


Hope these methods help.

Valve Employees: EA Attempted Buyout for Over $1 Billion

DICE. BioWare. Pandemic. Playfish. PopCap. The list of interactive entertainment studios (or their parent companies) purchased by Electronic Arts over the last decade runs the gamut from established triple-A developers to budding social-media game upstarts.

According to a new story published by The New York Times, however, the oft-infamous acquisitioner has, for quite some time, had its eyes set on what would have been its largest grab to date: fellow industry giant Valve.

The article, published yesterday and offering a rare glimpse into the quixotic corporate culture of the Valve, cited testimony from two anonymous Valve employees claiming to have knowledge of private discussions between their firm and Electronic Arts. According to the employees, EA had attempted to purchase Valve for years, and was prepared to value the company at “well over” $1 billion if the talks had ever become substantial.

Valve founder and current head Gabe Newell wouldn’t acknowledge any potential offers, but he indicated that a buyout – no matter how lucrative – wasn’t part of his company’s future vision. Conversely, he suggests, the individualistic nature of Valve’s employees would see it “disintegrate” before submitting to any outside ownership:

“It’s way more likely we would head in that direction than say, ‘Let’s find some giant company that wants to cash us out and wait two or three years to have our employment agreements terminate.’ ”

With the company’s ever-growing interest in hardware design also referenced in the story; Steam Big Picture looking to further connect the PC with the TV (the Big Picture beta was released today, as it happens); and Half-Life 3 rumors persisting; Valve’s status as an easy buyout candidate appears as it always has with Newell at the head: nonexistent.
