Me and my friend just bought the game but we cant start it. We get the Backend Error without any code and the only Option we have is to close the game…

im from Germany so maybe my English is a bit false at some point…sorry for that.
I bought the Game last Wednesday (10.31.2018) together with 3 Friends. I installed the Game and now i cant start it. I get the loading screen (fat shark, Games Workshop etc.) but then only the Message Back-End-Fehler 1000 (Fehler means error in German). So please help me solve this Problem. I have already 45 minutes of “playtime” because i tried everything to fix this (guess i startet the Game about 30 Times now).


thank you very much,

Hey Deathshop, I suspect your issue is related to Easy Anti-Cheat.

Please try repairing Easy Anti-Cheat via the EasyAntiCheat_Setup executable located here: C:\Program Files (x86)\Steam\steamapps\common\Warhammer Vermintide 2\installers\EasyAntiCheat

sorry, i see that’s the wrong chanel -->sorry.
When i open EasyAntiCheat, i can repair it … i do it. Now i open the game again, but i can’t play in the Official Realm . :frowning:
I closed my Virenscanner (Gdata) in german “Antivirusprogramm” but i cant start the official realm.
I uninstall the game, and downloading again, but i cant start it…
Sometimes i get an error befor i get the Launch Error -->

Game Security Violation Detected (#0000000Dh)[LightingService.exe]
Game Security Violation Detected (#0000000D)[LightingService.exe]

I do not know anymore what I can do.

I purchased the game this evening and played it, had issues after the first tutorial type portion of the game and couldn’t play after that. deleted the save file, redid it and had the same problem. now im just getting this backend problem. I will put up all the logs in the hope that the backend issue and this other issue can be resolved in some way.
