I have a problem. I installed the game and patched it ( all works normal ) but if i go to options, my game crashes. I need to be in the option menu to change the resolution.
The lowest resolution of my screen = 800*600 =) . and the game always starts with a lower resolution.

Is there a way to change my ingame resolution without running it ?

Yes, there is. In the registry, go to HKEY_CURRENT_USER\Software\Team17SoftwareLTD\Worms Armageddon\Options and edit the "DisplayXSize" and "DisplayYSize" values. Note that if your monitor/video driver doesn't support the sizes you chose, WA will revert to 640×480.

I tried changing these resolutions settings in the registry, but it still crashes everytime I select options. I'm running a Dell Inspiron with 15.4 wide screen. I've tried nearly every display dimension available, with no luck. Any other ideas?
