It was running fine yesterday. Now, I get that, after the updater runs. Anybody?

IIRC, it's something to do with some DirectX funkiness, and you have to switch into the OpenGL renderer. Not sure of the specifics though.

a1k0n accidentally dynamically linked in a bad lib. He just fixed it. :)

If you're in Windows,
go into your Vendetta directory and try deleting your config.ini file.
Also, if it fails to initialize directx, it will automatically try opengl. So you don't need to manually go into opengl mode if the game doesn't run. (I hope that makes sense)

I have the same problem, and i deleted the config.ini file, but nothing happens, still comes up the same thing. I didnt realy understand what you meant with that other thing

I had the same problem on windows, I removed the newest NVIDIA driver and put on the one that came out in February/March, and vendetta worked again.
